摘要：A clamshell-type electrophotographic image forming apparatus wherein a drumcartridge (4) by which a photosensitive drum (5) is supported is removably

accommodated in a clamshell-type opening/closing unit (2) provided on a base plate (1)

so as to be opened and closed. The position of a drum shaft (6) of the photosensitivedrum (5) is limited by positioning device (K) which operates according to the opening orclosing, or accommodating or removal of the clamshell opening/closing unit. The drumcartridge (500) is permitted to be attached or detached in a direction at right angles withthe axial direction of a support shaft (702) about which a clamshell opening/closing unit(700) turns and the developing cartridge (D) is permitted to be attached or detached in adirection in parallel with the axial direction of the support shaft (702). A drive gear (804)of the developing unit (D) is opposed to a drive gear (805) of the side of a main body, andthe drum cartridge (500) that is attached, causes the developing unit (D) to be pushed,such that the drive gear (804) of the developing unit (D) meshes with the drive gear (805)of the side of the main, body.
