Abstract: A receiving member is configured to receive a driving force from outside, is mounted on a first side wall on an opposite side from a developer accommodating portion, and is rotatable around a first axis line parallel to the longitudinal direction. A rotating member is rotatably provided between the first and second side walls, and configured to be rotated by the driving force received by the receiving member. A detection body is mounted on the second side wall on an opposite side from the developer accommodating portion and includes a detected part which is detected by a detecting unit. The detection body advances outwards in the longitudinal direction with respect to the second side wall and retracts inwards in the longitudinal direction with respect to the second side wall by the driving force received by the receiving member.

Abstract: 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.
