7、上的潜像区吸引碳粉，从面形成可见的碳粉图像。wDeveloping is to convert the electric latent image into visible toner image at the developing station.Toner is attracted onto the mag sleeve magnetically from the toner hopper,and charged via friction between the mag sleeve and the doctor blade.The doctor blade also evenly met
8、ers the toner amount on the mag sleeve.An AC/DC voltage give the toner a negative charge bias and transfers the toner to the OPC图像形成等四步：转印Image Formation Stage Four：Transferring携带碳粉图像的鼓转动，并与同样速度的纸相遇。转印辊给纸背面施以正的电压，使带负电的碳粉被吸引到纸上。The drum with toned image rotates and contacts with the media that delive
