    Abstract: A fixing apparatus includes a heating unit configured to heat an endless belt stretched around a plurality of rollers, a lower pressure roller pressed into contact with the fixing belt, and a control unit configured to control the temperature of the fixing belt by controlling the heating unit, and fixes an unfixed toner image formed on a continuous paper to the continuous paper by heat from the heated object under a nipping pressure applied at the nip portion which is formed by engagement between the fixing belt and the lower pressure roller. The control unit controls the temperature of the fixing belt to be a stand-by temperature lower than such a first temperature, which is set up in advance, that paper trouble might occur if the continuous paper is continuously heated at a temperature not lower than the first temperature in a stand-by state in which fixing is not performed.

    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 that forms an image on a transfer material in an image forming mode, includes: a photoreceptor rotatable in a predetermined rotation direction; a developer that forms a toner image on the photoreceptor using a two-component developing agent including toner and a carrier; a transferor that transfers the toner image on the photoreceptor onto the transfer material; a carrier collector that applies an electric field corresponding to a collecting bias to a carrier adhering to the photoreceptor to collect the carrier; a carrier detector that detects a carrier remaining on the photoreceptor after collecting the carrier by the carrier collector; and a hardware processor that sets the collecting bias in the image forming mode on the basis of the amount of carriers detected by the carrier detector when a carrier adhesion detecting mode for forcibly causing a carrier to adhere to the photoreceptor is executed.
