Abstract: The exposing unit emits a pair of light beams deflected to reverse scanning directions each other by a rotary polyhedron. The pattern creation unit creates color misregistration detection patterns on the transfer unit by the toner image in a reference color formed by a light beam emitted from an exposing unit and the toner image in an adjustment color formed by the other light beam having a different scanning direction. The color misregistration collection unit, on the basis of the image forming position of the toner image in the reference color, moves an image forming position of the toner image in each color formed by the light beam having the scanning direction opposite to the light beam corresponding to the reference color according to the color misregistration adjustment amount detected by the adjustment amount detection unit.

Abstract: An image forming apparatus includes an image carrier, a charging device, an exposure device, a developing device, a transfer portion, a cleaning blade, and a control section. The control section detects a charging current amount of the image carrier and, when an integrated current amount obtained by integrating values of the charging current amount in a prescribed length of time is lower than a prescribed threshold value, performs an aging process in which the image carrier is driven to rotate in a charged state.

Abstract: The neutralization units 12a and 12b are arranged between the primary transfer positions and the cleaning units 11a and 11b, and, irradiate a region on the image supporting body 2a with first neutralization light 131, the regions spanning from a position facing the primary transfer position to a position facing the cleaning unit 11a. The neutralization units 12a and 12b irradiate a region on the image supporting body 2b with second neutralization light 132, the region spanning from a position facing the developing unit 16b to a position facing the primary transfer position. The neutralization units 12a and 12b include a first reflective part and a second reflective part provided at different positions on a side face of the light guiding body. The first reflective part forms the light 131 and the second reflective part forms the light 132 by reflecting the light from the neutralization light source.

Abstract: A developing device includes a developing container, a first stirring member and a second stirring member, and a developing roller. The developing container includes a first stirring chamber, a second stirring chamber, and a communication portion. The first stirring member includes a reverse spiral vane that conveys a developer in a direction reverse to a circulation direction. An air discharge duct is formed on a wall portion of the first stirring chamber opposed to the reverse spiral vane and in an area excluding the communication portion and discharges air from the first stirring chamber to an outside of the developing container via an air discharge port at a distal end of the air discharge duct. A filtration portion is disposed in the air discharge duct adjacently to the air discharge port and restricts leakage of the developer through the air discharge port.

Abstract: A cleaning device has a housing where an opening and a toner storage portion are formed, a cleaning member arranged in the opening, a collection roller collecting toner attached to the cleaning member, a blade scraping off toner attached to the collection roller, a sheet member dividing between the toner storage portion and the opening, and a sealing member arranged to be in contact with the housing and both end parts of the outer circumferential surface of the collection roller in the axial direction. A first region having a predetermined surface roughness is formed in a middle part of the circumferential surface of the collection roller in the axial direction, and a second region having a lower surface roughness than the first region is formed next to both end parts of the first region in the axial direction.

Abstract: The image forming apparatus includes an image carrier, a charging unit, an exposure unit, a developing unit, a transfer unit, a cleaning blade, and a controller. The controller detects printing-coverage rates on a basis of plural areas divided in the longitudinal direction of the image carrier. At a specified timing, the controller executes aging process in which the image carrier in a charged state is driven into rotation under light irradiation by the exposure unit. For the aging process, the controller sets a condition that a light quantity of the exposure unit for an area of larger coverage rate is larger than a light quantity of the exposure unit for an area of smaller coverage rate.

Abstract: The image forming apparatus includes an image carrier, a charging unit, an exposure unit, a developing unit, a transfer unit, a cleaning blade, and a controller. The controller detects printing-coverage rates on a basis of plural areas divided in the longitudinal direction of the image carrier. Upon occurrence of a difference exceeding a specified threshold value among the coverage rates of the plural areas, the controller executes, for a duration of specified aging time, aging process in which the image carrier is driven into rotation in its charged state.
