Patent ID: 8019236

Claim:
An image forming device, comprising: a fixing part having a transporting mechanism that transports a paper, on which a toner image is formed, in a forward direction towards a downstream side while thermally fixing the toner image; a first paper detecting part disposed on an upstream side of the fixing part; a second paper detecting part disposed on a downstream side of the fixing part; a paper jam detecting part that detects a paper jam in the fixing part when a paper is not detected by the second paper detecting part within a first prescribed time after the paper is detected by the first paper detecting part; and a transportation control part which drive-controls the transporting mechanism to effect the following operations during a period of transporting the paper in the forward direction: changing a transporting direction of the paper to a reverse direction in response to concurrence of the following two conditions: a paper jam in the fixing part being detected by the paper jam detecting part; and a rear end of the paper having passed the first paper detecting part so as not to be detected by the first paper detecting part at a time concurrent with indication of the paper jam by the paper jam detecting part; and stopping transport of the paper in response to concurrence of the following two conditions: a paper jam in the fixing part being detected by the paper jam detecting part; and the paper being detected by the first detecting part at a time concurrent with indication of the paper jam by the paper jam detecting part.
