Patent attributes
An image forming apparatus of the present invention carries out an image processing with respect to image information which is to be printed. The image forming apparatus predicts the occurrence of an image elongation which may occur due to slippage of a recording material with respect to the electrostatic image drum, and specifies an image elongation occurring area on the basis of a printing ratio of the image information. If the occurrence of slippage, and thus image elongation is predicted, the amount of the image elongation occurring area to be shortened is calculated. The image information is then modified to obtain write image information that is shortened based on the calculated shortening amount. This write image information is then used to form the electrostatic latent image that is developed and transferred to a recording material. Thus, even slippage does occur, it is possible to accurately form the desired image on the recording material.
