Abstract

A roll shaft comprises a roll core, an elastic buffer layer and a function layer, wherein the elastic buffer layer sleeves the roll core; the function layer sleeves the elastic buffer layer. The permanent compression set value of the function layer is larger than that of the elastic buffer layer. The roll shaft is simple to manufacture, and low in cost. Besides, the invention further provides a manufacturing method for the roll shaft.

Description

technical field [0001] The present invention relates to printing / copying equipment, and more particularly to a roller shaft and a manufacturing method thereof. Background technique [0002] A laser printer is composed of a laser, an acousto-optic modulator, a high-frequency driver, a scanner, a synchronizer, and an optical deflector. Its function is to modulate the binary dot matrix information sent by the interface circuit on the laser beam, and then scan to the photosensitive physically. The photosensitive body and the camera mechanism form an electrophotographic transfer system, which transfers the graphic image shot on the photosensitive drum to the printing paper, and its principle is the same as that of a copier. A laser printer is a non-impact output device that combines laser scanning technology and electronic imaging technology. A charging roller, a photosensitive roller, a laser scanning mechanism, a developing device, a transfer roller, a fixing roller, and the ...
