Abstract
An image forming apparatus includes a developing device, a toner tank configured to receive toner supplied from a toner cartridge mounted in the image forming apparatus and to supply the toner to the developing device, a first toner sensor configured to detect a first toner residual level in the toner tank, a second toner sensor configured to detect a second toner residual level lower than the first toner residual level in the toner tank, and a processor. The processor is configured to count a number of times the first toner sensor switches from a non-detection state to a detection state subsequent to the second toner sensor switching from a detection state to a non-detection state, and then output a notification indicating a residual amount of toner in the toner cartridge based on the counted number.
