Abstract
An image forming apparatus includes: a carrier configured to carry developer; a voltage applying unit configured to apply a voltage to the carrier so that a carrier current flows from the voltage applying unit through the carrier; and a current detecting unit configured to detect the carrier current. The current detecting unit detects the carrier current at an uncharged portion of the carrier.
