Background

The laser printer outputs characters or images through interaction by using physical and chemical principles of light, electricity and heat. The basic process can be divided into seven steps of charging, exposure, development, transfer, fixing, cleaning, and discharging. First, the photosensitive drum surface is uniformly charged by the charging roller. The laser scanner emits modulated laser light containing image information to the photosensitive drum, and forms an electrostatic latent image corresponding to an image to be copied on the surface of the photosensitive drum. Then, the toner from the developing roller is adsorbed on the surface of the photosensitive drum, so that the electrostatic latent image is converted into a visible image. As the photosensitive drum rotates and a positive voltage is applied to the back surface of a recording medium such as paper via the transfer roller, an attractive force is generated to the negatively charged toner forming a visible image on the surface of the photosensitive drum, and the visible image formed from the toner is transferred to the recording medium such as paper. Then enters a fixing component formed by a heating roller and a pressure roller, and carbon powder particles are fused into fibers of the recording medium under the action of heat and pressure, so that a visible image formed by the carbon powder is completely solidified on the recording medium, namely, the basic imaging action is completed.

In the above-described image forming process, the quality of the charging roller and the developing roller of the process cartridge is an important factor for ensuring the image quality. The charging roller or the developing roller is generally configured such that a metal core shaft having good conductivity is disposed in the middle, and a conductive or semiconductive rubber tube, which is foamed or unfoamed, is coated on the outer surface of the metal core shaft. The rubber tube is sleeved on the mandrel, so that the charging roller and the developing roller are generally called rubber rollers.
