Abstract

A charger has a cylindrical rotation tube coming in contact with an image receptor on which a toner image is formed, the rotation tube to which a predetermined charge bias is applied, and drive means for driving the rotation tube at a predetermined peripheral speed, the charger for uniformly charging the surface of the image receptor. When the peripheral speed of the image receptor is V1 and the peripheral speed of the rotation tube is V2, the following relation is satisfied: 1.01<(V2 / V1)<=1.10.

Description

technical field

[0001] The present invention relates to a method for charging the surface of an image carrier such as a photoconductive drum on which a toner image is formed with a uniform potential in an image forming apparatus such as an electrophotographic copier or a laser beam printer. A charger, in particular, relates to an improvement for keeping the surface of an image carrier and the surface of a charger in a clean state for a long period of time. Background technique

[0002] In an electrophotographic copier or a laser beam printer, the surface of an image bearing member such as a photoconductive drum is uniformly charged, and then exposed according to image information to form an electrostatic latent image, and the electrostatic latent image is formed in the toner Development is performed to form a toner image of a visible image, and finally, the toner image is transferred to an image carrier such as an intermediate transfer body or recording paper to form a recor...
