摘要： A controller controls a replenishing operation of the first replenishing device based on the first sensor, and controls a replenishing operation of the second replenishing device based on the second sensor. The controller prohibits the replenishing operation of the first replenishing device when the developer concentration in the first replenishing device reaches a first upper limit set to the first developing device, and the controller prohibits the replenishing operation of the second replenishing device when the developer concentration in the second replenishing device reaches a second upper limit set to the second developing device. The controller corrects the second upper limit based on the developer concentration in the second developing device when the developer concentration in the first developing device reaches the first upper limit.

摘要： An image forming apparatus includes an image bearing member for bearing an image, a developing device for developing with a toner an electrostatic image formed on the image bearing member, and a detecting portion for detecting environmental information. In addition, a storing portion stores the environmental information, and a controller controls an image forming condition on the basis of the environmental information detected in a last detection and current detection. The controller controls the image forming condition so that a change amount per unit time of the image forming condition when the developing device is driven is made larger than a change amount per unit time of the image forming condition when the developing device is stopped.

摘要： A developing apparatus includes a developer carrying member, a regulating member configured to regulate developer carried on the developer carrying member, and a partition wall separating a first chamber and a second chamber. A first conveying screw conveys the developer in the first chamber, and a second conveying screw conveys the developer in the second chamber. The first conveying screw is at a position overlapping with a vertical line passing through a portion of the regulating member, and a periphery of the first conveying screw moves in the same direction as a peripheral surface of the developer carrying member that is faces. The vertical line overlaps with a part of a rotation region of the first conveying screw in which the periphery of the first conveying screw is moved in a downward direction.
