ABSTRACT:
An image forming apparatus includes toner image forming devices for forming toner images of a plurality of mutually different colors, a toner image carrying member for carrying thereon the toner images of the plurality of colors to be transferred onto a recording medium at one time, an adhesion amount detection device for detecting a toner adhesion amount of each of the toner images, and a failure determination device for determining the presence or absence of a sign of failure in the toner image forming devices. The failure determination device determines the presence or absence of the sign of failure in one of the toner image forming devices on the basis of information based on adhesion amount detection results obtained through detection by the adhesion amount detection device of toner adhesion amounts of toner images formed on the toner image carrying member by the other toner image forming devices.
