发明名称 IMAGE-FORMING APPARATUS
摘要 PROBLEM TO BE SOLVED: To correct a skew without losing image data. SOLUTION: The image-forming apparatus includes a plurality of image stations having photosensitive bodies and developing means set corresponding to develop colors, a plurality of exposure means for irradiating respective photosensitive bodies with light to form latent images, a transfer means for sequentially overlapping and transferring toner images of each color formed at the plurality of image stations to a transfer material, thereby forming a synthetic image on the transfer material, an engine control part 13 for controlling the apparatus in operation, and a VSZA and a VSZB signals indicating a printing effective area formed for each color to a sub scanning direction as a transfer direction of the transfer material and having different active periods, one of which is a printing effective area indication signal in the sub scanning direction whereby the active period for the engine control part 13 is extended by the number of lines increased by a skew correction process.
