<p>PURPOSE: To provide an electrophotographic device, which can prevent the feeding of a paper sheet curled more than the regulation in a paper carrying passage so as to previously prevent the generation of paper jam in the paper carrying passage and which is coupled with a paper sheet curl correcting mechanism so as to perform the stabilized carrying of the paper sheet. CONSTITUTION: A paper sheet 11 is carried in a paper carrying passage by a carrying roller 12 and a pressure roller 13 in the condition that it is curled upward or downward. At this stage, an optical distance sensor 14 provided in the paper carrying passage detects direction and quantity of curl of the paper sheet 11. In the case where the tip of the paper sheet 11 is curled upward, when the tip of the paper sheet 11 passes under the sensor 14, the paper sheet 11 comes closest to the sensor 14 surface, and separated from the sensor 14 surface, as it is carried away. In the case where the tip of the paper sheet 11 is curled downward, the paper sheet 11 is passed in the opposite condition.</p> |
