    Abstract: The exposing unit emits a pair of light beams deflected to reverse scanning directions each other by a rotary polyhedron. The pattern creation unit creates color misregistration detection patterns on the transfer unit by the toner image in a reference color formed by a light beam emitted from an exposing unit and the toner image in an adjustment color formed by the other light beam having a different scanning direction. The color misregistration correction unit, on the basis of the image forming position of the toner image in the reference color, moves an image forming position of the toner image in each color formed by the light beam having the scanning direction opposite to the light beam corresponding to the reference color according to the color misregistration adjustment amount detected by the adjustment amount detection unit.

    Abstract: A developing device includes a developing roller, a toner supply roller, a regulating blade, a casing, and a cleaning member. The developing roller supplies a toner to the image carrier in a region opposed to an image carrier. The toner supply roller is located opposed to the developing roller. The toner supply roller forms a magnetic brush made of a two-component developer including a magnetic carrier and a toner on an outer peripheral surface to supply a toner to the developing roller in a region opposed to the developing roller. The regulating blade is located opposed to the toner supply roller at a predetermined interval. The casing houses the developing roller, the toner supply roller, and the regulating blade. The cleaning member reciprocates along a longitudinal direction of the regulating blade so as to remove a toner accumulated on a top surface of the regulating blade.

    Abstract: A developing device includes a developing container, a first stirring member and a second stirring member, and a developing roller. The developing container includes a first stirring chamber, a second stirring chamber, and a communication portion. The first stirring member includes a reverse spiral vane that conveys a developer in a direction reverse to a circulation direction. An air discharge duct is formed on a wall portion of the first stirring chamber opposed to the reverse spiral vane and in an area excluding the communication portion and discharges air from the first stirring chamber to an outside of the developing container via an air discharge port at a distal end of the air discharge duct. A filtration portion is disposed in the air discharge duct adjacently to the air discharge port and restricts leakage of the developer through the air discharge port.
