According to one embodiment, an apparatus includes a photoconductor, an exposure device, a developing device, a toner concentration sensor, a supply motor, and a processor. The exposure device exposes the photoconductor based on image data. The developing device forms a toner image on the photoconductor with toner supplied from a toner cartridge. The toner concentration sensor detects a toner concentration in the developing device. The supply motor supplies the toner from the toner cartridge to the developing device based on the toner concentration. The processor detects a toner container supply abnormality based on a toner supply rate and a print rate of the image data, the toner supply rate being calculated based on a pixel count value that is an integrated value of pixel values of the image data and a supply motor count value that is an integrated value of drive times of the supply motor.
An image forming apparatus, comprising:
A method for controlling an image forming apparatus including a photoconductive image carrier, an exposure device that exposes the photoconductive image carrier based on image data, a developing device that forms a toner image on the photoconductive image carrier by toner supplied from a toner cartridge, a toner concentration sensor that detects toner concentration in the developing device, a toner supply motor that supplies the toner from the toner cartridge to the developing device based on the toner concentration, and a processor, the method comprising:
A toner processing system, comprising:
