An image forming apparatus which forms on a recording paper a visible image in accordance with image data, the forming being performed by using an electrophotographic method, and the apparatus being able to reduce a total recording time spent for recording one page as compared to the present technology. The image forming apparatus comprises a processing unit, comprising a photosensitive drum on which a latent image is formed while the drum is being rotated at a predetermined rotational speed, for processing the image data so as to form the visible image, a conveying unit for conveying the recording paper to/from the processing unit, a driving unit for driving the photosensitive drum and the conveying unit, and a controlling unit for controlling the driving unit so that the rotational speed of the photosensitive drum is changed based on a length of the visible image being formed on said recording paper. A processing time spent on a blank part of the recording paper being reduced by effecting an increase in the rotational speed of the photosensitive drum.
