IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes an exposure control unit that performs control, based on a shift-amount of an exposure position from an ideal position, the shift-amount being obtained from a detection-result of a misregistration correcting pattern image, to shift at least one of an exposure timing corresponding to first image data which is input to one of two electric cables in contact with a target electric cable and an exposure timing corresponding to second image data which is input to another one of the two electric cables, with respect to an exposure timing corresponding to target image data being input to the target electric cable both sides of which are in contact with the two other electric cables, among a plurality of the electric cables which corresponds respectively to a plurality of the exposure units provided for each of a plurality of colors.

1. An image forming apparatus comprising:
an exposure unit that performs exposure according to image data and forms a latent image based on the image data on a photoconductor; a detection unit that detects a misregistration correcting pattern image formed on an image bearer being driven at a predetermined speed; a calculation unit that calculates a correction amount according to a result of detection of the misregistration correcting pattern image performed by the detection unit, the correction amount indicating an amount of shift of an exposure position from an ideal position; and an exposure control unit that performs control, on the basis of the correction amount, to shift at least one of an exposure timing corresponding to first image data which is input to one of two electric cables in contact with a target electric cable and an exposure timing corresponding to second image data which is input to another one of the two electric cables, with respect to an exposure timing corresponding to target image data which is input to the target electric cable indicating the electric cable, both sides of which are in contact with the two other electric cables, among a plurality of the electric cables which corresponds one-to-one to each of a plurality of the exposure units provided for each of a plurality of colors, to which image data of a corresponding color is input, and which is connected to a corresponding one of the exposure units.
