An image forming apparatus includes: a process cartridge; a voltage applying unit; a contact; an electric line; a detection unit; and a control unit. The voltage applying unit generates a voltage and applies the voltage to the process cartridge. The contact is switched an ON state and an OFF state based on a usage state of the process cartridge The electric line electrically connects the voltage applying unit to the process cartridge. The detection unit is electrically connected to the electric line via the contact and provides either one of a first detection output corresponding to the ON state and a second detection output corresponding to the OFF state. The control unit executes a determination process in a determination mode for determining the usage state of the process cartridge based on either one of the first detection output and the second detection output of the detection unit.
