Abstract
A process cartridge having: a photosensitive drum; a drum unit comprising the photosensitive drum; a developing roller configured to deposit toner on the photosensitive drum; a developing unit comprising the developing roller; an elastic component; a retaining component. The elastic component is configured to bias the developing unit, from developing position to separation position. When the developing unit is in the separation position and a first coupling member rotates, the retaining component is configured to move in response to rotation of the first coupling member, thereby causing a protrusion to disengage from a abutment part to allow the developing unit to move from the separation position to the developing position.
