PROBLEM TO BE SOLVED: To provide a cleaning device making the negative charge, the current flowing in a paper sheet transfer roller or the like prevented as a result of the electric charge injection to toner at the time of cleaning the paper sheet transfer roller. SOLUTION: This is the cleaning device cleaning the toner 7 stuck on the paper sheet transfer roller 25. Accordingly, the device is provided with the cleaning roller 26 consisting of a base material part 26a provided with conductivity and a resistor layer 26b being formed on a periphery of the base material part 26a provided with a specified electric resistance formed on a periphery of the base material part 26, and rotating held in contact with the paper sheet transfer roller 25. The device is provided with a cleaning power source 27 applying cleaning bias voltage in polarity opposite to the static charge polarity of the toner 7 to the base material 26a. Moreover, the device is provided with a cleaning blade 31 removing the toner 7 shifted from the paper sheet transfer roller 25 to the surface on the resistor layer 26b of the cleaning roller 26. |
