Abstract

The present invention provides an image forming apparatus, including: an image carrier configured by a positively charged single-layer electrophotographic photosensitive body; a charging device which is based on a contact charging method for charging a circumferential surface of the image carrier while making contact with the circumferential surface of the image carrier; and a transfer unit which transfers a toner image on the circumferential surface of the image carrier to a transfer receiving body by gripping the transfer receiving body with the image carrier, wherein the transfer unit includes an application unit to which a transfer bias is applied, and a region having a volume resistivity of 10to 10Ω·cm exists between the image carrier and the application unit.
