PURPOSE:To reduce the cost by simplifying an assembly while increasing the strength, by forming the circumferential wall of the end part of a photoreceptor in one body as a driven gear. CONSTITUTION:Photoreceptor 20, having flanges 21a and 21b fitted at both ends, is pivoted on supporting shaft 23 via bearings 22. At one end of photoreceptor 20, driven gear 20a is formed in a body, and gear 20a has a prescribed tooth shape and a prescribed number of teeth and is formed simultaneously with the formation of photoreceptor 20. Base plate 24 is provided with bearing tools 26 pivoting driving shaft 28 rotatably; at one end of shaft 28, main driving gear 29 engaging with the driving source is provided and at the other end, gear 30 engaging with gear 20a is also provided. As gear 29 rotates, gears 30 and 20a rotate and photoreceptor 20 also rotates to perform copy. |
