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 8):
The image forming apparatus according to  claim 1 , wherein the hardware processor\n judges whether or not the developer in the casing is uniform, based on the amount of change per unit time of the output value of the sensor repeatedly acquired at a time interval equal to a stirring cycle which is a cycle in which the developer in the casing circulates in the casing by stirring of the screw.
