Abstract: A transfer unit includes first and second rollers of which the second roller has an elastic layer larger in the axial direction than the first roller, a roller holder, and a switching cam. One of the first and second rollers is, by rotating the roller holder, arranged opposite an image carrying member and, by rotating the switching cam, arranged selectively either at a reference position to form a transfer nip or at a released position to lie away from the image carrying member. Let a length of the elastic layer of the first roller in the axial direction, a width of an effective image area on the image carrying member to which a toner image can be transferred, and a width of a recording medium of a maximum size allowing transfer using the first roller be L1, L3, and L4 respectively, L4

Abstract: A fixing device includes a fixing member, a pressing member, a cover, and a separation member. The cover is movable between a closing position at which a conveyance path is formed and an opening position at which the conveyance path is exposed. The cover includes a recess. The separation member is movable between a contact position at which the separation member comes in contact with a face of the fixing member and a withdrawing position at which the separation member is separated from the fixing member. The separation member separates a medium from the face of the fixing member in a state in which the separation member is arranged at the contact position. A tip end part of the separation member enters an interior of the recess of the cover in a state in which the separation member is arranged at the withdrawing position.

Abstract: An image forming apparatus includes a roller pair, a paper dust collecting member, a scraping member, and a paper dust receiver. The paper dust collecting member can be drawn out from the apparatus main body and is disposed along an axis direction of the roller pair so as to collect paper dust adhered to one roller of the roller pair. The scraping member scrapes off paper dust adhered to the paper dust collecting member when the paper dust collecting member is moved in a draw-out direction. The paper dust receiver is disposed below the scraping member so as to receive the paper dust scraped off by the scraping member.

Abstract: A fixing device includes a heating belt, a pressing roller, a pressing member and a cap. The pressing member faces an inner circumferential face of the heating belt via a lubricant. The cap is rotating together with the heating belt. The cap has a disk part, a cylindrical part, a gear and a hole part. The cylindrical part has an inner circumferential face coming into contact with the outer circumferential face of the heating belt. The gear is formed integrally with an outer face of the disk part. The hole part penetrates from the inner circumferential face of the cylindrical part to a face between adjacently disposed teeth of the gear. The lubricant flowed from the inner circumferential face of the heating belt to the outer circumferential face of the heating belt flows to a tooth surface of the gear through the hole part.

Abstract: A fixing device includes a heating member, a pressing member, a pressing mechanism and a locking mechanism. The heating member is rotatable. The pressing roller is configured to come into contact with the heating member. The pressing mechanism is configured to convert a rotational force transmitted from a drive source to a pressing force of pressing the pressing roller against the heating member and to form a pressing region between the pressing roller and the heating member. A sheet is conveyed through the pressing region. The locking mechanism is configured to be engaged with an image forming apparatus main body linked with a pressing operation of applying the pressing force to the pressing roller and to be disengaged from the image forming apparatus main body linked with completion of a pressing release operation of removing the pressing force.

Abstract: A sheet conveying device of the present disclosure includes: a conveying portion that conveys a sheet in a conveying direction directed toward an image transfer position; a detection portion that detects a conveyance deviation of the sheet conveyed; a sheet correction portion provided on a downstream side of the conveying portion in the conveying direction; and a speed control portion that controls a displacement speed of the sheet correction portion during a displacement process of the sheet correction portion from a sheet acceptance position to a correction completion position. The speed control portion causes the sheet correction portion to be displaced to a setting position set between the sheet acceptance position and the correction completion position at a predetermined first speed, and causes the sheet correction portion to be displaced from the setting position to the correction completion position at a second speed lower than the first speed.

Abstract: An image forming apparatus includes an image forming portion, an image input portion, a transfer unit, a transfer voltage power supply, and a control portion. The transfer unit includes a transfer roller having a metal shaft and an elastic layer laid around an outer circumferential face of the metal shaft to form a transfer nip by keeping the elastic layer in pressed contact with an image carrying member, and transfers a toner image formed on the image carrying member to a recording medium as it passes through the transfer nip. The transfer unit includes, as the transfer roller, a first roller, and a second roller having a larger axial-size elastic layer compared to the first roller. The control portion arranges the first or second roller opposite the image carrying member according to width-direction sizes of the recording medium and image data fed to the image input portion.
