ABSTRACT:
An electrophotographic photoreceptor comprising an electrically conductive substrate having thereon a subbing layer and a photosensitive layer in sequence, wherein the subbing layer is a layer formed by using a hydrolyzable compound, the layer having a residual organic group content of at least 25 mol % based on the total organic group content of the hydrolyzable compound used, or (ii) by coating a solution of the hydrolyzable compound in an organic solvent in which the hydrolyzable compound has been hydrolyzed to a degree of at least 50%. The coating composition exhibits satisfactory film-forming properties to form a subbing layer without causing cracks which thereby provides an electrophotographic photoreceptor with excellent stability on repeated use.
