Abstract
The image forming apparatus includes a conductive member provided in a conveying path of a recording material, a voltage applying device for applying a voltage to the conductive member, a current detecting device for detecting a current flowing in the conductive member when the recording material passes through the conductive member to which a voltage is applied by the voltage applying device, and a judgment device for judging, based on an output from the current detecting device, whether a conductive foreign object is present on the recording material. Thus there is provided an image forming apparatus capable of detecting a foreign object attached to a recording material by a simple method.
