摘要:
In the field of the photosensitive member for electrophotography comprising an electrically conductive substrate and at least one primer layer and a photosensitive layer, there is disclosed an improved member which is characterized in that the primer layer contains a copolyamide which contains as a constituent a diamine represented by a chemical formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 respectively and independently a hydrogen atom or a methyl or ethyl group.
摘要:
An amorphous silicon photoreceptor for electrophotography having a specific surface roughness is disclosed herein. Also provided are a process for the preparation and/or regeneration of the material and improved methods for electrophotography, which use a special abrasive. The material enables the electrophotography without occurance of any image blurring under high humidity conditions.
