PURPOSE:To use a sheet-like photoreceptor which is easily taken in charge and generates no fold, by providing a comb-shaped electrode on the surface of a belt- like insulator, and impressing DC voltage to this electrode. CONSTITUTION:An insulator 4 constituted like a belt is extended to belt driving rolls 1, 2 and 3, and comb-shaped electrodes 5, 5' are provided on the surface of this insulator 4. Also, the comb-shaped electrodes are covered with an insulating film 7 by leaving both ends 6, 6' of the comb-shaped electrodes 5, 5'. DC high voltage of 3-7KV is impressed through a brush to both the ends 6, 6' of the comb-shaped electrodes. Subsequently, a sheet-like photoreceptor 8 having a conductive film on its back is wound from on the comb-shaped electrodes 5, 5' covered with the insulating film 7. In this way, the sheet-like photoreceptor 8 is attracted to the comb-shaped electrodes 5, 5', therefore, is fixed onto the belt- like insulator 4. |
