Abstract
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.
