<p>Provided is an electrophotographic photoreceptor that exhibits high transfer resistance and excellent memory and electric properties. Also provided are a method for producing said electrophotographic photoreceptor, and an electrophotographic device. The electrophotographic photoreceptor is provided with an undercoat layer (2) and a photosensitive layer (3) which are disposed on a conductive base (1) in said order. The photosensitive layer (3) contains at least a phthalocyanine compound as the electric charge generating material, and contains, as the resin binder, a polyvinyl acetal resin comprising a repeating unit represented by general formula (1). (In formula (1), R represents a hydrogen atom, a methy group, an ethyl group, or a propyl group; x, y, and z each represent the mol% of the respective structural units and x+y+z=100; n represents an integer between 1 and 5; the acetylation degree (x+z) is 76 to 99 mol%; and the mol ratio (x:z) of the structural units is 95 to 50:5 to 50.)</p> |
