PURPOSE:To remove quickly and easily jammed transfer paper, and also to set precisely an interval between a photosensitive body and a developing sleeve by providing a rotary drum freely attachably and detachably in a prescribed direction, and a developing device freely turnably respectively. CONSTITUTION:A rotary drum 14 having a photosensitive body on the surface is mounted vertically to a revolving center axis and freely detachable in the direction toward a developing device 20. On the other hand, the developing device 20 is mounted freely turnably and can be turned clockwise by the own weight of the developing device. Therefore, a spacer ring provided on the developing device is made to contact with the surface of the drum 14. Accordingly, the jammed transfer paper can be removed quickly and easily by moving the drum 14 to the right against deviating force by the own weight of the developing device 20. Also, the interval between the photosentivie body and a developing sleeve can be set precisely by the spacer ring. |
