Abstract
A photosensitive drum is rotatable about a drum axis extending in a first direction. A frame includes a first side plate located at first end in the first direction and a second side plate spaced from the first side plate in the first direction. The frame rotatably supports the photosensitive drum between the first side plate and the second side plate in the first direction. The frame holds a developer cartridge. A lock lever is pivotable about a pivot axis extending in a second direction intersecting with the first direction. The lock lever is movable between a lock position at which the developer cartridge is locked on the frame and a release position at which the developer cartridge is unlocked from the frame.
