Abstract: Provided is an image forming apparatus including an image carrier, an exposure device, a developing device that supplies a developer to form a toner image, and a hardware processor that controls the image carrier, the exposure device, and the developing device. The image forming apparatus further includes a fume prevention plate that covers a part of an internal space of the developing device where the developing roller is disposed and the developer is stored and that prevents the developer from scattering outside from the internal space, a suction duct, and an air suction device. One end of the suction duct is connected to the internal space and another end of the suction duct is connected to the air suction device. The fume prevention plate includes a movable portion. A position of the movable portion can be changed between a first position and a second position different from the first position.

Abstract: A developing apparatus includes a developer carrier that carries a developer, and a developer casing that contains the developer to be supplied to the developer carrier. An opening/closing part is capable of controlling a moving amount of the developer between a first region on one side in an axial direction of the developer carrier and a second region on the other side in the axial direction of the developer carrier by opening or closing the first region and the second region. A hardware processor controls an open/closed state of the opening/closing part in accordance with the state of the developer in the first region and the second region.
