PROBLEM TO BE SOLVED: To reduce the generation frequency of a paper sheet jam by detecting a temperature and humidity at the time of peeling a paper sheet wound to a photoreceptor by a peeling means and changing the set value of a peeling current by using the matrix chart of the temperature and the humidity. SOLUTION: When the paper sheet 10 roughly wound to the photoreceptor 3 is rolled up or the paper sheet 10 is carried in the state of being roughly stuck to the photoreceptor 3 and a tip is rolled up, a jam is generated in a paper sheet traveling path. Then, the temperature and the humidity are detected for fixed time at every certain fixed interval of time by a temperature/humidity sensor 11 installed inside a machine and the pertinent part of the matrix chart is increased/decreased for a reference value based on the highest value of the temperature/humidity obtained there. In this case, the temperature/humidity sensor 11 of the peeling means, a high voltage power source 12, a controller 13 and a peeling set value matrix 14 detect the temperature and the humidity at the time of peeling the paper sheet wound to the photoreceptor 3 and change the set value of the peeling current by using the matrix chart of the temperature and the humidity. |
