Apparatus for duplicating or printing.

摘要

An image forming apparatus includes an image carrying body for carrying a latent image, a developing device for applying a developing agent to the latent image to form a developing agent image on the image carrying body, a transferring device for transferring the developing agent image from the image carrying body onto a printable area of a recording medium. In the apparatus, a ratio of area of developing agent on the image carrying body to the printable area of the printing medium is detected. The developing device is controlled to apply the developing agent to the image carrying body to forcibly adhere the developing agent onto the image carrying body when the ratio is smaller than a specified ratio. <IMAGE>
