PROBLEM TO BE SOLVED: To provide a positively chargeable single layer type electrophotographic photoreceptor little in tendency to cause film damage and superior in durability by enhancing the adhesion between a conductive substrate and a photosensitive layer. SOLUTION: The electrophotographic photoreceptor is formed by laminating, on the conductive substrate 1, an interlayer 2 made of a copolymer made from a primary resin component of vinyl chloride and a secondary resin component of vinyl acetate in an amount of <=10 weight % and a tertiary resin component, and the photosensitive single layer 3 containing a charge generating material and a positive hole transfer material and an electron transfer material and a binder resin. The tertiary resin component is embodied by one or two selected from among maleic acid, acrylic acid, vinyl alcohol, and hydroxyalkyl acrylate. The interlayer 2 contains fine metal oxide particles, preferably, those of titanium oxide.
