  • Publication number: 20100322644
    Abstract: An image forming apparatus includes a remaining amount information acquiring unit, a toner sensing unit, and a determination unit. The remaining amount information acquiring unit acquires remaining amount information on an amount of toner remaining in a cartridge, which is stored in a memory device disposed in the cartridge mounted on an image forming apparatus body. The toner sensing unit senses information on an amount of toner in a developing device performing a developing process using the toner supplied from the cartridge. The determination unit determines that the toner in the cartridge is empty when the remaining amount information acquired by the remaining amount information acquiring unit indicates that the remaining amount is smaller than a predetermined amount of toner and the information on the amount of toner sensed by the toner sensing unit indicates that the amount of toner in the developing device is smaller than a predetermined amount.
