Abstract:
The image bearing member to improve transfer efficiency at an occasion of transferring a toner image from the image bearing member. A rotational speed of a motor rotating the image bearing member in a short period and thereby disorder in a toner image can be restrained to reach a low level. On the other hand, circumferential velocity between the image bearing member and paper can be provided large. Therefore improvement in transfer efficiency can be designed.
