ABSTRACT:
An image forming apparatus for forming images on both surfaces of a recording sheet. It is discriminated from image signals obtained by scanning a first surface and a second surface of an original which surface has more or less toner consumption, and the image formation sequence is controlled so that an image, which has been judged to have less toner consumption, is first formed on the first surface of the recording medium while an image, which has been judged to have more toner consumption, is formed on the second surface of the recording sheet afterward. Also, in the formation process of the image, which has been judged to have less toner consumption, the fixing roller is not coated with anti-offset liquid, but in the formation process of the image, which has been judged to have more toner consumption, it is controlled so that the fixing roller is coated with the anti-offset liquid.
