The flexible member is a sheet-like member having flexibility, and is attached to the base body such that the flexible member covers, via a gap, a range of the base body from a front end surface facing the developer carrying body to an upper surface, and a bent portion covering a boundary portion between the front end surface and the upper surface of the base body is closer to the outer circumferential surface of the developer carrying body than the other part is.

Abstract: A developing device 43 includes a first rotation control portion and a second rotation control portion. When a developing process is performed, the first rotation control portion causes a developer carrying member to rotate in a first rotation direction at a first rotation speed previously determined. When the developing process is not performed, the second rotation control portion causes the developer carrying member to rotate at a second rotation speed V2 faster than a rotation speed V1 during the developing process in a direction X2 reverse to a development rotation direction X1, and then, causes the developer carrying member to rotate at a third rotation speed V3 slower than the second rotation speed V2 in the direction X2.

Abstract: An image forming apparatus includes an image carrier, a developer carrier, a bias applying section, a leakage detecting section, and a bias controlling section. The developer carrier carries developer in the form of a layer of magnetized filaments to supply toner to the image carrier. The bias applying section applies to the developer carrier a development bias including a direct current voltage VmagDC and an alternating current voltage VmagAC superposed on each other. The leakage detecting section causes a discharge between the image carrier and the developer carrier and detects a leakage voltage when the discharge occurs. The leakage detecting section performs the leakage voltage detection in a blank region of the image carrier bearing no electrostatic latent image. The bias controlling section determines an alternating current voltage VmagAC according to a detected leakage voltage, and a frequency of the alternating current voltage VmagAC according to the voltage VmagAC.
