Abstract:
A developing device of an image forming apparatus includes a casing, two-component developer accommodated in the casing, and a stirring screw for conveying and stirring the developer in the casing by rotation in a predetermined direction. The image forming apparatus includes a toner concentration sensor that outputs a value indicative of the toner concentration of the developer in the casing. The image forming apparatus determines whether or not the developer in the casing has become uniform, based on the amount of change per unit time of the output value of the toner concentration sensor, acquired after the stirring of the developer in the casing by the stirring screw is started. It is possible to appropriately measure the reference value of the toner concentration.

Claim (Index 1):
An image forming apparatus comprising a developing device, wherein the developing device comprising:\n a casing, two-component developer accommodated in the casing, and a screw that conveys the developer in the casing in a predetermined direction and stirs the developer in the casing by rotating the screw, wherein the image forming apparatus comprising: a sensor that outputs a value indicative of toner concentration of the developer in the casing, and a hardware processor that judges whether or not the developer in the casing has become uniform, based on an amount of change per unit time of the output value of the sensor, acquired after start of stirring the developer in the casing by the screw.
