<P>PROBLEM TO BE SOLVED: To realize stable image quality and the prolongation of the service life of a sheet type photoreceptor by preventing image data from being written in the same part on the photoreceptor every time and reducing the optical fatigue of the photoreceptor. <P>SOLUTION: In the electrophotographic device using a photoreceptor drum equipped with a drum pipe stock, the sheet type photoreceptor wound round the drum pipe stock, and a cap member for holding the photoreceptor on the drum pipe stock, a laser write starting position from the cap member is shifted in each cycle, and paper feeding time is lagged corresponding to the positional shift of the laser write starting position. <P>COPYRIGHT: (C)2004,JPO |
