Title: Image forming method with various densities
Inventor: OKAMOTO YUJI
IPC: G03G21/00
Filed: 1987-12-18
Abstract: PURPOSE:To obtain an image with various densities by projecting light possessing energy causing photosensitive bodies to be fatigued on any area before a 1st electrifying process. CONSTITUTION:When the light possessing energy causing the photosensitive bodies 11 and 12 to be fatigued is projected on said bodies 11 and 12 before the 1st electrifying process, spatial charges arise in the deepest part of a photoconductive layer 11. When 1st electrification is performed, the spatial charges in the deepest part are attracted to surface charges to float, which cancels part of the surface charges to lower a surface potential. This is dark attenuation. When such light is projected on any area of the photosensitive bodies to cause dark attenuation, only the surface potential of the area concerned drops to reduce toner adhesion. As a result, image density can be pale.
