Abstract: PURPOSE:To obtain an electrifying device whose constitution is simple and which can carry out sure cleaning by cleaning a discharge member following its rotation in the electrifying device provided with the discharge member which performs electrification while rotating. CONSTITUTION:When the number of copies reaches a previously set number, a motor 19 is driven to be rotated at proper time, for example, at waiting time until image-forming becomes possible after a main switch is turned on, and a gear 17 moves to the right in the figure and abuts on a ring on the right side, thereby rotating a spiral screw 15 being the discharge member. When the gear 17 moves to the right, the holder 21 of a cleaning member 20 moves to the right through a projecting part B, the member 20 is engaged with the screw 15, thereafter, the member 20 moves along a guide rail 22 in a state where it is engaged with the screw 15 and performs cleaning. When the holder 21 reaches a sensor 23 at an end, the sensor 23 detects it and the motor 19 is reversely rotated to restore the holder 21 toward a home position. By repeating such actions, cleaning is performed.

Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To improve the crystallinity of a gallium nitride-based compound semiconductor by preventing the occurrence of warpage and cracking in the semiconductor. SOLUTION: A first layer 2 composed of SiO2 is formed on a silicon substrate 1 and the layer 2 has a grown area X and a non-grown area Y which are respectively formed in stripe- and grid-like states.
