    Abstract: An image forming apparatus includes a developing device that develops a latent image by causing toner to adhere to the latent image via a toner carrier disposed opposite a latent image carrier on which the latent image is formed. The developing device includes a drive transmitter that transmits a driving force to a toner conveyor that conveys the toner, and the drive transmitter performs switching between a first operation of transmitting the driving force for conveying the toner to the toner conveyor and a second operation of vibrating a preventer that is provided in the developing device and prevents the toner from scattering.

    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: An image forming apparatus includes an image former and a flattener. The image former forms an image on a recording medium. The flattener is disposed upstream of the image former in a conveying direction of the recording medium, and flattens the recording medium before the image former forms the image on the recording medium.

    IPC: G03G15/095

    Abstract: An image forming apparatus includes an image carrier that carries a toner image, a developer that develops a toner image on the image carrier, with a developing agent containing toner and carrier, a transferor that transfers the toner image being carried by the image carrier, a collection mechanism that collects the carrier on the image carrier by a magnetic force and an electrostatic force, and a hardware processor that controls removal of the toner adhering to the collection mechanism. The collection mechanism includes a collection roller that incorporates a magnet and that is rotatable while facing the image carrier, and a voltage applicator that applies a voltage to the collection roller. The hardware processor performs a toner removal mode to remove the toner, by setting a peripheral speed of at least one of the image carrier and the collection roller to less than a peripheral speed thereof for image formation.
