Abstract: A developing unit is detachably mounted on a photosensitive unit to form a combined unit called a process unit. In use, the process unit is loaded into an electrophotographic image forming device. A rotational shaft of a photosensitive drum projects out from the photosensitive unit. When the process unit is loaded into the image forming device from a top open space, both ends of the rotational shaft are engaged with a pair of guides formed in side walls of the image forming device and guided down along the guides. The process unit is accommodated in an accommodating section when both ends of the rotational shaft have been brought into abutment with stops at the ends of the guides and a trailing end of the process unit is rotated downward about the rotational shaft.

Abstract: A photosensitive unit is described. The photosensitive unit may include a developer cartridge including a developing agent carrier and a casing, a photosensitive member, and a side wall. The casing is provided with a pivoting member including a pressuring portion applied with an external pressing force and a fitting projection fitted to the side wall. The pivoting member is configured to be pivoted along a pressing direction for pressing the developing agent carrier toward the photosensitive member when a pressing force is applied to the pressuring portion, or along a pressure releasing direction opposite to the pressing direction. The side wall is formed with a fit portion to which the fitting projection is loosely fitted so that a movement of the fitting projection along a pivoting direction of the pivoting member is allowed.
