Title: Electrophotographic photoreceptor and method of producing the same
Inventor: OKADA SATOSHI
IPC: G03G5/08
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To solve a problem of an amorphous silicon photoreceptor with addition of boron such that when the add amount of boron is increased, the photosensitivity is improved but sufficient electrification performance is not obtained and that when the add amount of boron is decreased, the electrification performance is improved but sufficient photosensitivity is not obtained. SOLUTION: The aforementioned problem is solved by providing a method of producing an amorphous silicon electrophotographic photoreceptor described below. When a film of the amorphous silicon photoreceptor is formed, the add amount of diborane gas introduced with the source gas into a plasma CVD device is controlled to a specified range according to the thickness of the amorphous silicon photosensitive layer. Moreover, the boron concentration in the surface side region of the amorphous silicon photosensitive layer is controlled to show the gradient with higher concentration in the substrate side and lower in the surface side.
