Abstract
An image forming apparatus includes a transferring belt, photosensitive drums along the belt, primary transferring parts transferring images from the drums to the belt, voltage applying parts applying transfer voltages to the respective transferring parts when each transferring part carries out transfer, a current detecting part and a resistance value measuring part. When the measuring part carries out resistance value measurement, if one transferring part is a measurement subject of the measuring part, the applying part applies zero or weak voltage to the one transferring part and applies the transfer voltage to other transferring parts at measurement timing when the one transferring part is between sheets. At the measurement timing, the detecting part detects a first total current value of currents flowing thorough the transferring parts and the measuring part measures the subject resistance value of the one transferring part based on the first total current value.
