Abstract: A photosensitive drum unit includes a frame and a plurality of photosensitive drums. The plurality of photosensitive drums is supported by the frame and has a shape identical with one another. Each of the plurality of photosensitive drums is rotatable about a rotational axis. The plurality of photosensitive drums is arranged such that a distance between rotational axes of adjacent photosensitive drums is a constant distance P. Each of the plurality of photosensitive drums has a circumferential reference position that is common to all of the plurality of photosensitive drums. Each of the plurality of photosensitive drums has a plurality of marks at circumferential positions that are defined relative to the circumferential reference position. Adjacent two positions of the circumferential positions are spaced by a central angle of {(S−P)/S}×360° where S is a circumferential length of each of the plurality of photosensitive drums.

Abstract: A laser printer includes a contact/separation mechanism that linearly moves developing cartridges between contact positions where the developing cartridges contact corresponding photosensitive drums and separating positions where the developing cartridges separate from the photosensitive drums. The contact/separation mechanism includes a pair of contact/separation members and a synchronous moving mechanism. The contact/separation members are disposed one on one side of the developing cartridges and another on another side of the developing cartridges. The synchronous moving mechanism is for linearly moving the contact/separation members in synchronization with each other.

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.
