PURPOSE:To easily attach/detach an electrifying roller without making cost high because of the increase of the number of parts. CONSTITUTION:This photoreceptor unit is formed so that a photoreceptor 10 and the electrifying roller 11 rotating while being in contact with the photoreceptor 10 are laid between a pair of opposed side plates 18, and both ends of the photoreceptor 10 and the roller 11 are rotatably supported by the side plates 18. Attachment/detachment ports 19c through which the roller shaft 20 of the roller 11 passes at the time of attaching/detaching the roller 11 and guide grooves 19d long in the radial direction of the photoreceptor 10 are successively provided on the opposed side plates 18. When the roller 11 is attached/ detached, the roller shaft 20 is attached/detached through the ports 19c. |
