PROBLEM TO BE SOLVED: To provide an electrophotographic device capable of obtaining high printing durability and high-resolution picture quality even when a photoreceptor having a large-film-thickness charge transfer layer of≥25μm which tends to decrease resolution is loaded in the electrophotographic device, and to provide a cylindrical electrophotographic photoreceptor used for the device. SOLUTION: The electrophotographic device is equipped with a cylindrical stacked electrophotographic photoreceptor and an electrophotographic process member arranged in the vicinity of the cylindrical surface of the photoreceptor, and makes the process member function to form an image while rotating the photoreceptor. Relational inequalities (1) and (2) hold for the peripheral velocity V (mm/second) of the photoreceptor, the contact angle A (degree) of the photoreceptor surface to pure water, and the film thickness T (μm) of the charge transfer layer of the photoreceptor.
