Abstract
The present invention relates to an electrophotographic sensitive member, in particular to an electophotographic sensitive member, in which a residual potential is reduced and a background smearing is prevented from being produced, and further to an electrophotographic sensitive member capable of carrying out a high-speed copying suitable for a semiconductor laser beam printer. A photosensitive member used in instruments, such as super-high-speed coying machine and laser beam printer, is used for a long time at a high-speed, so that the stability and durability are required for the operation. To this requirement, amorphous silicon hydride has been watched with interest in view of heat-resistance, abrasion-resistance, anti-pollution, photosensitive characteristic and the like. However, also a multi-layer type photosensitive member or a separated function type photosensitive member, which has been known as an electrophotographic sensitive member formed of this amorphous silicon hydride, has shown a problem of residual image that the preceding image is not completely removed to be remained by an optical memory effect and appears again in the formation of the following image when it is…
