PURPOSE:To safely and easily remove a photoreceptor and to provide a unit of a lever number, a belt unit, etc. on a bracket which is freely mountable and dismountable, by spacing a transfer paper separating part from the photoreceptor by rocking the lever member that can be interlocked to the separation of a charger member etc. CONSTITUTION:If a destaticizer 5 is pulled out in the direction perpendicular to the plane of the paper and is removed from the body, one end of a driving lever disengages from said destaticizer and therefore a separation operating lever 18 rocks in the counterclockwise direction around a shaft 21. A transfer paper separating plate 14 engaged with the pin 19 of the end 18E of the lever 18 is pushed downward and detaches from an electrostatic drum photoreceptor 1. Hence, said photoreceptor 1 is easily removable. To clean a turn belt 16, removing the separating plate 14, then disconnecting the screw at the other end of the shaft 21 a lever unit is removed together with a bracket 22.
