Abstract: A drum unit is provided, which includes a frame configured such that a development cartridge including a pressed portion is detachably attached thereto, and a pressing member. The development cartridge is movable between a pressed state where the pressed portion is pressed by the pressing member when attached to the frame and a released state where the pressed portion is released from pressing of the pressing member when the development cartridge is attached to the frame. The pressing member includes a pressing section that contacts and presses the pressed portion when the development cartridge is in the pressed state, and a restriction section configured to, when the development cartridge is in the pressing state, restrict movement of the pressed portion in a released direction, in which the pressed portion moves when the development cartridge moves from the pressing state to the released state.

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 pressing member applies a pressing force to a trailing end in a direction which intersects a predetermined reference direction, allowing the pressing force to have both a first component in the predetermined reference direction and a second component perpendicular to the predetermined reference direction. A trailing end is pressed in the predetermined reference direction by the first component. In the mounted state, the leading end is in contact with the reference member at two contact surfaces including a first contact surface and a second contact surface. The first contact surface defines a first positioning direction being perpendicular to the first contact surface and intersecting the predetermined reference direction. The second contact surface defines a second positioning direction being perpendicular to the second contact surface and intersecting both the predetermined reference direction and the first positioning direction, allowing the photosensitive-member unit to be positioned with respect to the main body.
