Title: Electrostatic charging device
Inventor: ANDO YUJIRO
IPC: G03G15/02
Filed: 1992-06-17
Abstract: PURPOSE:To prevent the generation of the moire on an image by forming the impressing vibration voltage on an electrostatic charging member so as to prevent the generation of the moire on an image by the unequal period of the electrostatic charge potential occurring in an AC voltage by working the electrostatic charging member in such a manner that the end on the downstream side in the surface moving direction of a member to be electrostatically charged is nonlinear. CONSTITUTION:The outer peripheral surface of an electrostatic charging roller as the electrostatic charging member is provided with spiral ruggedness 111, 112 along its longitudinal direction and the contact surface Na with a photosensitive drum 10 as the member to be electrostatically charged has a plane shape as shown in Fig. (b). The electrostatic charging blade 11A is used in such a state that the edge parts at the front end of the saw tooth-shaped ruggedness are positioned on the downstream side in the surface moving direction of the photosensitive drum. Accordingly, the evenness of electrostatic charge generated on the drum 10 is rugged shape as well. The unequal electrostatic charge is therefore nonlinear with the image of the linear repetitive patterns perpendicular to the surface progressing direction of the member to be electrostatically charged if the electrostatic charging device is used as an electrostatic charge treatment means for an image carrying member as the member to be electrostatically charged of an image forming device. The resemblance with the recorded image is thus eliminated and the generation of the moire is prevented.
