ABSTRACT:
An image carrier of an organic photosensitive material containing a charge-generating agent and a charge-transporting agent, and a transfer roller using an electrically conducting polyurethane rubber composition which is so cured as to exhibit a rubber hardness of higher than 50.degree. (JIS A), are disposed being spaced apart maintaining a small gap which is greater than the thickness of the transfer material enabling the toner to be transferred onto the transfer material. This makes it possible to prevent the occurrence of image defects such as white spots and the like, to form transferred image favorably and stably over an extended period of time maintaining a high density without fogging and consuming a small transfer current.
