PURPOSE:To make an image carrier attachable/detachable easy and to make it unnecessary to remove a charge erasing means from a picture formation device body by forming a means for shifting the charge erasing means. CONSTITUTION:An operation lever 15 is pushed in the arrow B1 direction and an LED array 16 is arranged close to a photosensitive drum 1. If the operation lever 15 is pulled in the arrow B2 direction, guide holes 24, 25 are also moved in the arrow B2 direction, the positions of pins 27, 28 are relatively slided in the arrow B1 direction and the operation lever 15, an LED supporting frame 20, a substrate 18, and an LED array 16 are unitedly vibrated by angle theta1-theta0 around a vibration shaft hole 22. Consequently, the LED array 16 is separated from the photosensitive drum 1 and attached/detached without applying damages to the photosensitive drum 1. Since the photosensitive drum 1 is not disengaged from the body when a notched part 31 of the operation lever 15 is not disengaged from an axial center adjusting plate 30, damages can be prevented more precisely. |
