ELECTROPHOTOGRAPHIC DEVICE AND PROCESS UNIT FOR ELECTROPHOTOHGRAPOHIC DEVICE

摘要

PURPOSE:To always keep the position of a photosensitive body with respect to an exposure means and a driving means constant and to form an excellent image by providing a positioning means in a process unit incorporating a photosensitive body attachably/detachably attached to an electrophotographic device main body. CONSTITUTION:When an exposure device main body 45 abuts on the process unit 100 and it is pressed by a coil spring 50, the process unit 100 is also pressed downward. Then, one end side of the unit 100 is positioned by making a drum shaft 16 abut on the bottom part of the U-shaped groove 54 of a supporting member 51. The other side end of the unit 100 is positioned by making the abutting part 15a of the side part of a unit plate 15 functioning as the case of the unit 100 abut on a driving system supporting member 62a supporting a driving gear 62 to a side plate member 2a. Thus, the photosensitive drum 11 attached to the unit 100 always keeps a fixed position with respect to an exposure device and a driving device.
