Image forming apparatus

A program for controlling an image forming apparatus which forms on an electrostatic latent image bearing member an electrostatic latent image based on image information, visualizes the electrostatic latent image by a developer so as to obtain a visible image, and causes a transfer device to transfer the visible image to a recording material at a transfer nip portion while conveying the recording material, the image forming apparatus including:

• image elongation predicting means for predicting the occurrence of an image elongation, in other words, predicting that, due to slipping of the recording material with respect to the electrostatic latent image bearing member at the transfer nip portion, the visible image transferred is lengthened in a direction in which the recording material is conveyed;
• deletion amount setting means for setting the amount of a rear edge portion to be deleted from the electrostatic latent image, the amount being set in accordance with the amount of the visible image lengthened due to the image elongation;
• and image rear edge adjusting means for deleting the rear edge portion of the electrostatic latent image if said image elongation predicting means predicts the occurrence of the image elongation, the program causing a computer to execute said image elongation predicting means, said deletion amount setting means and said image rear edge adjusting means.
