    摘要: An image forming apparatus includes a cartridge and a casing. The cartridge includes a photosensitive drum, a developing roller, a developing frame, and a drum frame. The developing frame is movable between a contact position and a separated position. A separating member provided on the drum frame acts on the developing frame, so that a reaction force is exerted in a reaction force direction. The casing includes a positioning member, an urging member, and a separation pressing member. The positioning member has a first surface and a second surface. The urging member is configured to urge an end portion of the photosensitive drum toward the positioning member in an urging direction. The first surface is configured to support the end portion at a position downstream of the urging direction. The second surface is configured to support the end portion at a portion downstream of the reaction force direction.

    摘要: An image forming apparatus includes a main casing and a cartridge detachably mountable therein. The cartridge includes a photosensitive drum and a developing roller disposed to oppose each other. The main casing includes: a metal frame for supporting the cartridge; a lock member supported to the metal frame and movable about a first axis to allow or restrict movement of the photosensitive drum relative to the metal frame; and a contact-separation member supported to the metal frame and movable about a second axis to allow contact and separation of the developing roller relative to the photosensitive drum. The lock member and the contact-separation member are aligned in an orthogonal direction orthogonal to an axis of the photosensitive drum such that the first axis is not overlapped with the contact-separation member or the second axis is not overlapped with the lock member in an axial direction of the photosensitive drum.

    摘要: In a cartridge, a housing has a developer accommodating portion and includes a first side wall and a second side wall. A coupling member is disposed at a position opposite to the developer accommodating portion with respect to the first side wall. A detection body is disposed at a position opposite to the developer accommodating portion with respect to the second side wall. A first driving force transmission member is positioned at the same side with the coupling member with respect to the first side wall, and transmits driving force from the coupling member to a rotating member. A second driving force transmission member is positioned at the same side with the detection body with respect to the second side wall, and transmits driving force from the rotating member to the detection body.

    摘要: A process cartridge is configured to be mounted in an apparatus main body along a predetermined mounting direction. The process cartridge may include a photosensitive drum; a drum drive input member into which a driving force for rotating the photosensitive drum is configured to be inputted; and a frame which holds the photosensitive drum and the drum drive input member. The frame includes a substantially cylindrical first protecting member which is formed on the frame. The first protecting member is configured to accommodate the drum drive input member, and project in a rotational axis direction of the photosensitive drum, wherein a projecting amount of a portion of the first protecting member which lies at a downstream side in the mounting direction is smaller than a projecting amount of a portion of the first protecting member which lies at an upstream side in the mounting direction.

    摘要: A developing unit and image formation device in which a developer carrier is reliably pressed towards and separated from an image carrier is described. A separation and pressing mechanism is provided for separating and pressing the developer carriers of developing cartridges installed in a drum unit onto image carriers. This separation and pressing mechanism has a pair of direct cam members. Each direct cam member has a release action portion that engages with the releasing projection of a developing cartridge when the developer carrier is to be separated from the image carrier. Each direct cam member may also have a pressing action portion that engages with the pressing projection of the developing cartridges when the developer carrier is to be pressed onto the image carrier.
