摘要： An optical scanning device includes a polygon mirror, a beam detector, a correcting unit, and a controller. The polygon mirror deflects and scans a light beam in a main scanning direction on a surface of an image carrier. The beam detector detects a beam position of the deflected light beam in a sub-scanning direction. The correcting unit calculates a correction amount of out-of-color registration based on the beam position, and corrects out-of-color registration in the sub-scanning direction based on the correction amount. The controller controls, during correction of out-of-color registration, a deflection speed of the deflector to be less than a deflection speed for writing a latent image on the surface of the image carrier.

When forming images, the control device reads the data for the most distant standard scan line and the bending correction values for the scan lines of the other colors stored in the memory device, and carries out correction so that the laser irradiation position coincides with the standard scan line in accordance with the correction values via the sub scan deflecting element.

摘要： An image forming device which allows reducing a linear velocity ratio of a developing roller against a sensitive body, which enables a pole pitch of a magnetic field generating layer to be miniaturized, and which generates a uniform and adequately thick toner layer on the developing roller. A toner regulating element formed by a sheet metal material having elasticity and non-magnetic characteristics elastically contacts a surface of the developing roller. The developing roller has an elastic body layer and a magnetic field generating layer having a minute pole pitch. The toner regulating elements serves to regulate a thickness of the toner layer without vibration induced from the pole pitch of the magnetic field generating layer. Thus, the toner layer can be uniform and of an adequate thickness, and reducing the linear velocity ratio of the developing roller against the sensitive body does not generate any drawbacks.
