ABSTRACT:
A cleaning unit used for cleaning the surface of a recording medium in an image forming apparatus, the cleaning unit having a head being moved so as to contact with and separate from the recording medium on the basis of the assessment of preset image forming conditions such as paper size, document size, and copy magnification, and a control section for moving the cleaning head at a detected appropriate time, wherein the cleaning head is released so as to avoid the dispersion of toner that is likely to spoil the image.
