    Abstract: An image forming apparatus includes: an image carrier rotatably supported; a lubricant supplier that supplies lubricant to a surface of the image carrier, a blade that levels the lubricant supplied from the lubricant supplier in a film-like form on the surface of the image carrier, and a controller that controls image formation, wherein the controller has a lubricant removal mode to remove the lubricant accumulated on the blade, the lubricant removal mode includes a plurality of displacement modes each of which imparts different displacement to the blade, in each of the displacement modes, one of a displacement amount, a displacement speed, a displacement period, a displacement angle, and a displacement position of the blade is different, and the controller performs switching between the displacement modes during execution of the lubricant removal mode.

    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.
