Image forming apparatus and tandem type photosensitive unit

摘要

An image forming apparatus is described. An image forming apparatus may include an image forming apparatus body and a tandem type photosensitive unit slidable with respect to the body, wherein the unit includes: a frame; a plurality of photosensitive bodies; a plurality of developer cartridges, including developer carriers, detachably mountable on the frame; and a pressing portion provided on the frame for pressing each of the cartridges so that the developer carrier thereof is directed toward the corresponding photosensitive body, each of the cartridges is pivoted to be movable to an imaging position pressed by the pressing portion and a detached position released from the pressing by the pressing portion, and the body is provided with an abutting portion abutting the cartridge located on the detached position thereby pivoting the cartridge and moving the same to the imaging position when the unit is mounted on the body.

主权项

1. An image forming apparatus comprising:
a main body; a tandem type photosensitive unit configured to be in a drawn out state in which the tandem type photosensitive unit is drawn out with respect to the main body, and configured to be in a mounted state in which the tandem type photosensitive unit is mounted to the main body, wherein the tandem type photosensitive unit includes;
a plurality of photosensitive bodies corresponding to a plurality of developer cartridges, each of the plurality of developer cartridges including a developer roller extending in a first direction;a plurality of pressing portions corresponding to the plurality of developer cartridges, each of the plurality of pressing portions configured to press a corresponding one of the plurality of developer cartridges toward a corresponding one of the plurality of photosensitive bodies;a frame configured to receive at least one of the plurality of developer cartridges in a first state in which at least one of the plurality of developer cartridges is pressed by a corresponding one of the plurality of pressing portions, and configured to receive at least one of the plurality of developer cartridges is released from a corresponding one of the plurality of pressing portions; and an abutting portion configured to contact each of the plurality of developer cartridges in the second state and configured to move each of the plurality of developer cartridges from the second state to the first state in a case where the tandem type photosensitive unit moves from the drawn out state to the mounted state.
