PURPOSE:To make it unnecessary to execute cleaning of a photosensitive drum by winding an insulating belt around the photosensitive drum which has formed an electrophotography photosensitive layer on the outside peripheral surface, and forming a toner image on this belt. CONSTITUTION:In case of a copying work, when an original is inserted between an original feed roller 17 and a nip roller 13, a photosensitive drum 30, a feed- out roller 34, a developing roll 41, etc. are all rotated synchronously at an equal speed, a lamp 47 is lighted, also electrostatic chargers 38a, 38b are operated, and an electrostatic latent image is formed on the photosensitive drum 30 and an insulating belt 31 and brough to toner development by a developing device 40. After a prescribed time, a feed paper roller 46 starts to rotate, a copying form moves in a state that it has adhered tightly to the insulating belt 31 by a transfer fixing roller 32 and a holding roller 33, and in that state, a toner image is transferred and fixed, and the copying form is fed out to the outside of a body 11. The toner remaining on the insulating belt 31 after the transfer is wiped off by a toner cleaner 51, and destaticized by a destaticizing brush 52. |
