PROBLEM TO BE SOLVED: To provide an electrostatic charging device in which a discharging gap formed in the neighborhood of a contacting place of an electrostatic charging member and a photoreceptor can surely and equally maintained. SOLUTION: Both of the ends of a flexible film 102 are supported and fixed by supporting members 103 to 105 to constitute an electrostatic charging member 101. This film 102 is in contact with a charged body 110 with comparatively small mechanical abutting force to form an area N. Then, when voltage is supplied from a power source 106, electrostatic attractive force larger than the mechanical abutting force is exerted on between a film 102 in the area N and the conductive base body 11 of the charged body 110. With this electrostatic attractive force, the film 102 in the area N is abutted so as to follow the charged body 110. Consequently, even when the charged body is recessed and projected, the electrostatic attractive force exerted on the film is nearly equal both in recessed parts and projecting parts, thereby the film is made to satisfactorily follow the axial direction of the charged body. Thus, the stable discharging gap is formed. COPYRIGHT: (C)2004,JPO
