Abstract

PROBLEM TO BE SOLVED: To enable the working of a roller surface with high accuracy and to work the roller surface with the good reproducibility of specific surface roughness by providing the device with a roller mounting section, a supporting means for supporting the roller, a polishing means for polishing an elastic layer and a fluid feeding means for feeding fluid. SOLUTION: A grinding wheel 2 is arranged to be pressed to the roller 1 and the supplying roller 3 is arranged to substantially face the polishing means and a roller contact direction. While the grinding wheel 2 is rotated at a speed of about 100rpm at a speed of about 1500rpm, the grinding wheel 2 is brought into contact with the elastic layer 1A of the roller 1 rotating at a speed of about 100rpm and is moved in this state from the one end side to the other end side of the roller 1, by which the elastic layer 1A is polished. Simultaneously therewith, the polishing dust of the supporting roll 3 and the roller 1 surface is blown away by a feeder for fluid, such as air, from an air nozzle 4 disposed in the position where the grinding wheel 2 substantially face the polishing surface for polishing the roller 1. Polishing dust is sucked away by a discharge device.

Description of the Related Art Generally, an electrophotographic apparatus and an electrostatic recording apparatus such as a copying machine and a printer have a drum-shaped photosensitive member (hereinafter referred to as a photosensitive drum). The photosensitive drum is charged and exposed to form an electrostatic latent image, and then toner is adhered and developed according to the latent image on the photosensitive drum, and then the toner on the photosensitive drum is transferred to recording paper or the like. The photosensitive drum is transferred to a recording medium and transferred. Thereafter, the photosensitive drum is discharged to a predetermined potential, and the toner remaining on the photosensitive drum is cleaned to prepare for the next printing. Further, the toner carried on the recording medium by the transfer is fused and pressed to fix the toner on the recording medium, thereby completing a series of recording operations.

[0003] Rollers such as a charging roller, a transfer roller, a developing roller, a cleaning roller, a developer conveying roller, and a paper feed roller in such an electrophotographic apparatus and an electrostatic recording apparatus have been developed with recent developments in electrophotographic technology. Various required characteristics have been imposed, one of which is the requirement to be able to accurately process the surface condition of the roller, and furthermore, the reproduction of a surface structure with a specific surface shape and roughness There is also a demand to get good. The reason why such required characteristics are required is that the hardness of the elastic layer of these rollers is reduced to 85 ° or less in Asker C scale, and the conventional processing method has such a soft elasticity. This is because it was difficult to process the layer with high accuracy and high reproducibility.

In general, as a conventional processing method, a method of grinding or polishing with a polishing means such as a cutting tool or a grindstone while rotating the outer peripheral surface of a roller is used. However,
In the above-mentioned conventional processing method, various vibrations are generated due to the contact between the outer peripheral surface of the roller and the polishing means, and when the condition setting is poor, these resonate in a specific frequency region and the roller is wobbled. ”And“ chatter ”.
Significant polishing scratches and irregularities occur on the outer peripheral surface of the roller. Also,
Polishing debris adhering to the outer peripheral surface of the roller hinders polishing, and there is a problem that desired dimensional accuracy, surface accuracy, and reproducibility of the roller cannot be obtained.
