<P>PROBLEM TO BE SOLVED: To provide an image forming device capable of effectively removing a foreign matter attached to a fixation member without using a cleaning member such as a cleaning roller or a cleaning brush. <P>SOLUTION: When a cleaning sheet 30 is fed into a fixation nip section N from an upstream side opening section 22a, the cleaning sheet 30 winds around a heating roller 16a with a second adhesive layer 35 facing outward. By driving a fixation roller pair 16 for a positive rotation for a predetermined period in this state, the second adhesive layer 35 contacts outer surfaces of a pressure roller 16b and a heat equalizing roller 27 in turn to transfer a foreign matter such as toner or a fine paper piece to the cleaning sheet 30 side. Also, when the fixation roller pair 16 is driven for a negative rotation, a sheet rear end section 31b of the cleaning sheet 30 winding around the heating roller 16a is hooked by a fixation feeding guide 23a to sequentially rewind the cleaning sheet 30 along the fixation feeding guide 23a. The cleaning sheet 30 is finally discharged from the upstream side opening section 22a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
