The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. An adjustment member is configured to shift each of the end portions of the rotation shaft to adjust a skew of the laser light.
Abstract:
A developing device of the present disclosure includes a developing roller, a toner supply roller, a regulation blade, a casing, a toner receiving support member, a toner receiving member, a vibration generation unit, and a vibration inhibition member. The toner receiving support member is disposed in the casing so as to be opposed to the developing roller or the toner supply roller in an area between the regulation blade and an image carrier. The toner receiving member has a toner receiving surface that receives toner dropping from the developing roller, and is supported so as to be swingable about an end edge thereof on a toner supply roller side as a fulcrum. In a state where the toner receiving member is not vibrating, the vibration inhibition member is in contact with each of both end portions of the toner receiving surface in a longitudinal direction thereof.
Abstract:
An inkjet recording apparatus includes a recording head, a conveyance section, a first voltage applying section, and a second power supplying section. The recording head ejects ink onto a recording sheet. The conveyance section conveys the recording sheet to a position of image forming by the recording head. The first power supplying section applies a voltage to the recording sheet upstream of the recording head in a conveyance direction of the recording sheet. The second power supplying section includes a plate member located between the recording head and the first power supplying section and applies a voltage to the plate member that is of opposite polarity to the voltage applied by the first power supplying section.
Abstract:
A conveyor device is for installation opposite to a recording head in a recording apparatus. The conveyor device includes a conveyor belt and a suction section. The conveyor belt conveys a recording medium. The suction section includes a guide member through which a plurality of through holes pass. The guide member has a surface having a plurality of grooves therein and facing the recording head with conveyor belt therebetween. The respective through holes are located in the respective grooves. The grooves include a plurality of grooves that extend in a direction across a conveyance direction of the recording medium. The suction section sucks on the recording medium through the conveyor belt and the guide member.
Abstract:
A conveyor device is installed opposite to a recording head in a recording apparatus. The conveyor device includes a conveyor belt that conveys a recording medium. The conveyor device further includes a suction section. The suction section includes a guide member having through holes and an air escape channel. The guide member is located opposite to the recording head with the conveyor belt therebetween. The suction section sucks on the recording medium through the conveyor belt and the guide member. The guide member has a surface having grooves therein. The surface faces the recording head with the conveyor belt therebetween. The surface has a recess located outside of a region where the grooves are located. The recess constitutes a part of the air escape channel. The air escape channel is in communication with one or more of the grooves.
Abstract:
A conveyor device is arranged to face a recording head. The conveyor device includes a conveyance belt and a suction section. The conveyance belt conveys a recording medium. The suction section includes a guide member that supports the recording medium through the conveyance belt. The suction section sucks the recording medium through a plurality of first holes passing through the guide member and a plurality of second holes passing through the conveyance belt to attach the recording medium to the conveyance belt. None of the first holes are formed in a first region of the guide member. The first region is a region where a partial region pertaining to a feeding member overlaps with a head facing region facing the recording head.
Abstract:
An inkjet recording apparatus includes a recording head, a conveyance section, a plate member, and a negative pressure applying section. The recording head ejects ink onto a recording medium. The conveyance section conveys the recording medium to a position of image forming by the recording head and has a conveying surface on which the recording medium is to be placed. The plate member is located upstream of the recording head in a conveyance direction of the recording medium to form a narrow gap with the conveying surface of the conveyance section. The negative pressure applying section applies negative pressure to the narrow gap. A distance across the narrow gap in a direction perpendicular to the conveying surface is set so as to allow air flowing into the narrow gap from surrounding space to have a higher flow velocity in the narrow gap than before flowing into the narrow gap.
Abstract:
A belt cleaning device includes a cleaning roller. The cleaning roller includes a roller having an outer peripheral surface. A sheet-like cleaning element is wound to the outer peripheral surface of the roller. One end part of the cleaning element is fixed to the outer peripheral surface of the roller. Both side edge parts in the other end part of the cleaning element are fixed to the outer peripheral surface of the roller. The both side edge parts in the other end part of the cleaning element are located on the outside of their region that is to face to possibly largest paper.
Abstract:
An inkjet recording apparatus includes a sheet feed section, an image forming section, a partition unit, an air inflow portion, a first sheet conveyance section, a second sheet conveyance section, and an air sucking and discharging section. The partition unit partitions an interior of an apparatus casing into a first space in which the image forming section is disposed and a second space in which the sheet feed section, the first sheet conveyance section, and the second sheet conveyance section are disposed. Air outside the apparatus casing is taken into the first space through the air inflow portion. The second sheet conveyance section includes a conveyance guide disposed downstream of the image forming section in a conveyance direction of a recording sheet. The air sucking and discharging section sucks air around the conveyance guide and discharges the air into the second space or out of the apparatus casing.
Abstract:
An inkjet recording apparatus includes a control section, a conveyance section, a recording head, a negative pressure applying section, a gap forming section, and a first voltage applying section. The conveyance section conveys a recording medium placed on a conveying surface. The negative pressure applying section applies negative pressure to holes in the conveying surface to suck the recording medium onto the conveying surface. The gap forming section forms a narrow gap, with the conveying surface, further upstream in a conveyance direction of the recording medium than the recording head. The gap forming section is composed of at least a part of a conductive portion. The first voltage applying section applies a voltage to the conductive portion. The control section controls the first voltage applying section to apply the voltage to the conductive portion while the inkjet recording apparatus performs a specific process.
