摘要： An image forming apparatus can prevent printed images from being degraded in image quality due to failure of the toner concentration to fall within a proper range, by correcting the deviations of the amount of toner consumption and the amount of toner supply depending on the individuality of each image forming apparatus and that enables exact identification of the cause of a fault associated with toner concentration, as well as providing an image forming method using the apparatus. A toner supply device supplies toner to a developing vessel through an opening in accordance with an instruction from a controller. The presence or absence of toner falling is detected based on the variation of the output from a magnetic permeability sensor when toner is supplied. The controller monitors the output voltage level of the magnetic permeability sensor and adjusts the input gain in accordance with the output voltage level to thereby control toner concentration.

摘要： An image forming apparatus includes: a developing device; a toner supply device that supplies toner to the developing device; a toner concentration controller that directs the toner supply device to perform toner supply to the developing device; and a toner empty determiner for determining that no toner is left in the toner supply device. The developing device includes a toner supply detecting sensor that detects whether toner is supplied from the toner supply device into the developer container, in the developer container. The toner concentration controller gives directions to perform the toner supply when the toner concentration of the developer in the developing device has become lower than a predetermined level. The toner empty determiner determines that the toner supply device has no toner left therein when no effect of the toner supply is detected by the toner supply detecting sensor after the toner supply is directed by the toner concentration controller. The toner supply detecting sensor is disposed in the preliminary agitating section.

摘要： A toner cartridge is a developer storage container for storing toner (developer) in a hollow cylindrical section that is driven to rotate on its axis so that the stored toner is discharged from an outlet. The cylindrical section has an inner circumferential surface provided with a plurality of liner protruding portions that extend in a direction tilted with respect to a rotation direction of the cylindrical section. Moreover, the toner cartridge includes a stirring member capable of moving in the cylindrical section so as to collide with the protruding portions. This makes it possible to stably supply a developer and to realize an inexpensive developer storage container whose size can be reduced.
