ABSTRACT:
In an image forming apparatus, a type of paper conveyed through a conveying path is determined based on combination of sensing signals obtained from a plurality of sensing units. Each of the sensing units is movable between an actuating position and a retracting position as a paper is conveyed through a conveying path. Based on the type of paper determined based on combination of sensing signals obtained from the plurality of sensing units, a control unit of the image forming apparatus controls an image forming unit forming an image on the conveyed paper.
