Abstract
The present invention relates to an electrophotographic sensitive member, in particular to a divided function type electrophotographic sensitive member formed of amorphous silicon and amorphous silicon carbide capable of particularly widening an optical band gap range to heighten an optical sensitivity. Stabilized operation characteristics and durability are required for an electrophotographic sensitive member drum carried on instruments such as a high-speed copying machine and a laser beam printer. As for these requirements, hydrogenized amorphous silicon is being watched with interest from the viewpoints of superior abrasion resistance, heat resistance, anti-pollution property, optical sensitive characteristic and the like. However, even multi-layer type sensitive member and a divided function type sensitive member, which have been known as an electrophotographic sensitive member formed of hydrogenized amorphous silicon, have shown problems in that in the case where they are used in the high-speed copying, a residual image, in which the preceding image remains without being completely removed by an optical memory effect and appears again with the formation of the subsequent image…
