JPS59195677A - Electrophotographic method - Google Patents

Abstract

PURPOSE:To form an electrophotographic method removing or reducing the light fatigue of an amorphous silicon type photoconductive layer by exposing and electrostatically discharging a transferred photosensitive body in a spectral wavelength area less than a specific wavelength to remove residual toner from the surface of the photosensitive body. CONSTITUTION:A photoconductive layer 2 is electrostatically charged with fixed polarity by a corona charger 3, an original 13 to be copied is lighted up by a lamp 4 and the photoconductive layer 2 of the original 13 is exposed through an optical system 6 to form an electrostatic latent image corresponding to the picture on the original. The electrostatic latent image is developed with toner by a developing means 8. Transfer paper 14 is fed so as to be contacted with the drum surface at the position of a toner transferring charger 9 and corona charged with the same polarity as the electrostatic latent image from the back of the transfer paper 14 to transfer the toner image to the transfer paper 14. The toner-transferred photoconductive layer 2 is completely exposed by a destaticizing lamp 11 having a spectral wavelength area <=600mmu wavelength to erase the residuel charge and then the residual toner is removed by a cleaning means 12.
