    摘要： An image formation apparatus is disclosed, capable of forming an image on both surfaces of a recording medium. The image formation apparatus is provided with the latent image forming unit for forming an unfixed image on the photosensitive drum, the transfer drum for transferring the unfixed image onto the recording medium, and an oil application device for applying a release agent onto the fixing roller. The release agent applied upon fixing the first surface is different in quantity from that applied upon fixing the second surface and the releasing agent applied to the fixing rotor during single side fixing is different in quantity than when both surfaces are to be fixed. The releasing agent quantity also differs depending on whether the apparatus is in cassette feed mode or manual feed mode and is not applied when the recording medium is in contact with the fixing roller.

    摘要： When a predetermined pattern (e.g. a pattern indicating the serial number of a copying machine) is added on an image formed on a recording paper, the image formation apparatus suppresses the appearance of fog by the addition of a predetermined pattern in the vicinity of the image. More particularly, a control circuit, which inputs and processes an image signal, estimates the leading and ending edge positions of the recording paper with respect to the transferring direction. The edge which is perpendicular to the transferring direction of the recording paper is determined based on a signal obtained from an ITOP generation circuit and a BD detector. Accordingly, an effective area for image formation on the recording paper is obtained and a modulation amount for adding the predetermined pattern is controlled in accordance with the position on the recording paper at which the predetermined pattern is added.
