Abstract
An image forming apparatus in which a toner image formed on an image bearing member is first transferred onto an intermediate transfer element and then onto a transfer member. A potential of the image bearing member is detected and a transfer bias voltage applied to the intermediate transfer element is controlled according to the potential of the image bearing member. Undesired images such as transfer blurring due to discharge at the first transfer area, and a solid image scattering and so-called crow's claw mark due to increase of resistance of the transfer member under low absolute humidities are improved.
