Stage: PROBLEM TO BE SOLVED: To provide a technique to perform appropriate supply control in an image forming apparatus configured to supply toner to a developing device that conveys toner against the gravity.SOLUTION: An image forming apparatus is used comprising: a developing device having an image carrier; a developer carrier that develops an electrostatic latent image on the image carrier with developer, a storage chamber that stores the developer below the developer carrier, and conveying means that rotates inside the storage chamber to convey the developer upward while stirring it; a supply device that supplies the developer to the storage chamber; detection means that detects the amount of developer based on the capacitance between conductive members inside the storage chamber; and a control unit that acquires information on a fluctuation range of the capacitance accompanying the rotation of the conveying means, when the information is equal to or more than a target fluctuation range, increases the amount of supply from the supply device, and when the information is smaller than the target fluctuation range, reduces the mount of supply.SELECTED DRAWING: Figure 15 (Grant)
