  • Patent number: 11899388
    Abstract: An image forming apparatus includes a main body, a development cartridge, a toner cartridge, and a controller. The development cartridge includes a development roller, a development chamber, and a development memory. The toner cartridge includes a case in which toner is stored, a toner supply unit configured to supply toner from the case into the development chamber, and a toner memory. The controller stores, in the development memory, information regarding a cumulative received toner amount and a cumulative toner consumption amount. The controller subtracts the cumulative toner consumption amount from the cumulative received toner amount to find a difference, and causes the toner supply unit to supply a first predetermined amount of toner into the development chamber when the difference is equal to or smaller than a first threshold value. The controller stores, in the toner memory, information regarding the cumulative supplied toner amount.
