ABSTRACT:
An image forming apparatus includes a transfer charger for electrostatically transferring a developing agent image formed on a photoconductive drum onto a paper sheet at a transfer position, and a separation charger for electrostatically separating the paper sheet from the drum. A convey guide is fixed to the separation charger so as to guide the paper sheet separated form the drum in a predetermined direction. The convey guide is formed of a material which is to be charged in a polarity opposite to a charge polarity of the developing agent on the paper sheet upon triboelectric charging between the convey guide and the paper sheet.
