Abstract

PURPOSE:To precisely control an electrostatically charged voltage on the surface of a photosensitive body by providing a voltage adjustment device which finely adjusts a grid voltage of a scorotron electrostatically charging device on the side of a cartridge which integrates image forming process parts. CONSTITUTION:The cartridge 2 which is freely loaded and unloaded is furnished in an image forming body device main body 1. A photosensitive body drum 7 and a scorotron electrifier 8, etc., are set in this cartridge 2. This electrifier 8 consists of a corona discharger 10 and a grid 11 and a high voltage coming from a high voltage device 4 provided in the main body 1 is impressed on the discharger 10. The voltage of a grid voltage generation device 3 provided in the main body 1 is impressed on the grid 11 through the voltage adjustment device 12 provided in the cartridge 2. This device finely adjusts the grid voltage to a specified voltage. Thus the electrostatically charged voltage of the drum 7 of each cartridge 2 can be adjusted beforehand and the color copying work of plural colors can be performed efficiently.
