Abstract

PURPOSE:To reduce fatigue of selenium even after long term use, by erasing an electrostatic latent image reamining on a selenium photoreceptor by the light having a spectral peak in wavelengths near 650-700nm. CONSTITUTION:Selenium photoreceptor 1 having photosensitivity to near the wavelengths of the ultraviolet region to 500nm and 650-700nm is uniformly charged by charger 2, then imagewise exposed to light from a light source containing the wavelengths of the ultraviolet region to 500nm to form a static latent image, and the latent image is developed with developing unit 7. The developed image is transferred with charger 10, and the light from incandescent lamp 11 is radiated through filter 13 for transmitting light near the wavelengths of 650-700nm to photoreceptor 1 to erase the static latent image remaining on photoreceptor 1.
