<P>PROBLEM TO BE SOLVED: To provide a slide contact member capable of permanently suppressing electric charge sounds which occur when directly bringing a contact charging member into contact with a photoreceptor drum and applying an AC voltage to charge the photoreceptor drum, even in a high-temperature environment, a photoreceptor drum having the slide contact member in its inside, a drum cartridge for electrophotography provided with the photoreceptor drum, and an image forming apparatus. <P>SOLUTION: The slide contact member is provided in the photoreceptor drum provided in the image forming apparatus including a charging device which is brought into contact with the photoreceptor drum to charge the photoreceptor drum and has a cylindrical shape having a slit and a constricted part formed extending in a longitudinal direction of the photoreceptor drum, and has a shape memory metal having a transformation temperature of 15 to 45°C installed in the constricted part. The photoreceptor drum has the slide member in its inside. The drum cartridge for the electrophotography and the image forming apparatus are provided with the photoreceptor drum. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
