Dust collection portions are installed at both ends of a holding plate installed on a shield plate of a charger. On the other hand, in a cleaning device, a dust collection member is installed so as to make contact with the shield plate and holding plate. Dust such as discharge products and toner occurred when moving the cleaning device and cleaning a sawtooth discharge electrode falls on the side of the charger where the holding plate of the shield plate is installed. The cleaning device, since the dust collection member is installed, cleans the sawtooth discharge electrode, simultaneously collects dust such as discharge products and toner on the shield plate by the dust collection member, and can collect dust in the dust collecting portions installed at both ends of the holding plate. By doing this, the grid can be prevented from adhering of dust and the print quality is prevented from lowering.
