Abstract

PURPOSE:To enable to prevent the adhering of dust on the screen with a simple constitution, by providing the electrostatic dust collection means near the opening of the enclosed body covering the screen shape photoreceptor. CONSTITUTION:In a copy machine, at the opening of modulation section of the enclosed body 2, the electrode 9 being the dust collection means is provided along both sides of the opening. A voltage is fed to this electrode 9 from the power supply 10, the polarity of this voltage is opposite with the charges of the toner in the device, allowing to adsorb the floated toner with it efficiently. Further, the electrode 9 is in removable free to the enclosure 2, allowing to make ease the maintenance.
