<P>PROBLEM TO BE SOLVED: To effectively prevent a transfer memory without adjusting a transfer current value. <P>SOLUTION: In a method for forming an image by using the organic photosensitive body of a positive charging type and by utilizing an inversion development system and a transfer bias potential, a relation between the thickness of a photosensitive layer and a potential difference on the surface of a photosensitive body in the case of main charging generated by the transfer memory is previously measured about each transfer current value in transferring about the photosensitive body. From the obtained relation between the thickness of a photosensitive layer and the potential difference, transfer current which shows a potential difference within ±10 V in an area where a thickness difference is not smaller than 15 μm is generated for performing transferring by applying the transfer bias potential. <P>COPYRIGHT: (C)2004,JPO |
