PURPOSE:To enable printing on special paper by changing a process speed in the case that it is judged by a paper judging means that a manual paper feeding is selected. CONSTITUTION:Judgement whether manual paper feeding or automatic paper feeding is selected is carried out by a paper supply judgement means M1, and when the selection of manual feeding is judged, a process speed is changed by a process speed control means M2. In the case that it is judged that specific paper such as envelopes, thick paper and the like are manually fed, for example, an image forming speed by a polygonal mirror and the like as well as a paper supply speed being the process speed by a roller and the like are for example reduced. It is thus possible to improve perform printing on such special paper. |
