PROBLEM TO BE SOLVED: To provide an electrophotographic device that can obtain uniform image density.SOLUTION: An electrophotographic device comprises: a cylindrical photoreceptor; charging means that charges a surface of the photoreceptor; ventilation means that vents a discharge product generated by the charge; exposure means that irradiates the surface of the photoreceptor with exposure light to form an electrostatic latent image on the surface of the photoreceptor; heating means that heats the photoreceptor; and a flange that is mounted so as to come into contact with end surfaces on both ends of the photoreceptor, and transfers drive force causing the photoreceptor to rotate. Arithmetic average coarseness on one end of the photoreceptor is Ra1[μm], and the arithmetic average coarseness on other end thereof is Ra2[μm] (where Ra1>Ra2), and the end surface whose arithmetic average coarseness of the photoreceptor is Ra1[μm] is provided on a side where an air volume of an air flow generated by the ventilation means increases.SELECTED DRAWING: Figure 2 |
