2.1 Electrophotographic processing mechanism2.1 电子影像处理机制
 (1) Electrophotographic process(1) 电子影像处理过程
The electrophotographic process is explained briefly below:电子影像处理过程的概述如下所示：
1. Charging充电过程
A voltage is applied to the CH roller to electrically charge the surface of the OPC drum.电压被加在CH棍上，从而使OPC硒鼓的表面上充负电。
2. Exposure曝光过程
The LED head radiates light onto the charged OPC drum in accordance with the image signal.根据图像信号，LED头将光线照射到充电后的OPC硒鼓的表面上。 The electric charge of the radiated part of the OPC drum surface attenuates depending on the intensity of the light, thus forming an electrostatic latent image on the OPC drum surface.被光线照射的OPC硒鼓表面上的电荷根据光线的强度而变化，就会在OPC硒鼓的表面上形成看不见的静电图像。
3. Development显影
Charged toner adheres to the electrostatic latent image of the OPC drum by electrostatic power, and forms a visible image on the OPC drum surface.由于静电的作用，带电的墨粉附着在OPC硒鼓表面上已形成的看不见的静电图像上，从而，在OPC硒鼓表面上就会形成看见的图像。
4. Transfer转印
Paper is placed over the OPC drum surface and an electric charge is applied to it from the back side by the transfer roller, so that the toner image is transferred to the paper.纸张被压向OPC硒鼓表面，然后，转印辊表面充上正电荷，从而，使墨粉形成的图像转印到纸张上。
5. Drum cleaning清理硒鼓
The drum cleaning blade removes toner remaining on the OPC drum after the transfer.在墨粉转印到纸张上之后，硒鼓清理刮片将OPC硒鼓上残留的墨粉清除掉。
6. Removal of Electricity清除静电
7. Belt cleaning清理转印皮带
The belt cleaning blade removes toner remaining on the belt.转印皮带清理刮片将转印皮带上残留的墨粉清除掉。
8. Fuser定影器
Heat and pressure are applied to the toner image on the paper to promote its fusion.向纸张上的墨粉图像加热加压，将图像定影在纸张上。
(2) Charging(2) 充电
A voltage is applied to the charging roller, which is placed in contact with the OPC drum surface, to charge the OPC drum surface.电压被加在与OPC硒鼓表面接触的充电辊上，因而，OPC硒鼓表面被充电。

(3) Exposure(3) 曝光
The light emitted from the LED head is radiated onto the charged surface of the OPC drum.从LED头发射出的光线照射到OPC硒鼓的表面上。 The charge of the radiated part of the OPC drum attenuates according to the intensity of the light, forming an electrostatic latent image on the OPC drum surface.被光线照射的OPC硒鼓表面上的电荷根据光线的强度而变化，就会在OPC硒鼓的表面上形成看不见的静电图像。

(4) Development(4) 显影
Toner adheres to the electrostatic latent image on the drum surface, thereby turning the electrostatic latent image into a toner image.带电的墨粉附着在硒鼓表面上已形成的看不见的静电图像上，从而，在硒鼓表面上就会形成看得见的图像。
1. The sponge roller allows the toner to stick to the development roller.海绵辊将墨粉附着在显影辊上。

2. The electrostatic latent image on the OPC drum surface is turned into a visible image by the toner.OPC硒鼓表面上看不见的静电图像就会通过墨粉转成看得见的图像。

(5) Transfer(5) 转印
A sheet of paper is placed over the OPC drum surface, and an electric charge is given to the paper from its back side by the transfer roller.将一张纸放在OPC硒鼓表面的上方，并且由转印辊向纸的背面施加电荷。
When a high voltage is applied to the transfer roller from the power source, the charge induced on the transfer roller moves on to the surface of the paper through the contact part between the transfer roller and the paper, the toner being attracted to the paper surface from the OPC drum surface.当从电源来的高电压施加在转印辊上后，通过转印辊与纸张的接触部分，转印辊上的电荷转移到纸的表面上，在静电的作用下，OPC硒鼓表面上的墨粉被吸附到纸上。
