The exposed area becomes conductive and discharges the surfac chanrge to round ,formin

3、g a electric latent image on the drum surface.圖像形成第三步:顯影Image Formation stage three developing在顯彫區(qū), 碳粉圖像。感光鼓表而的靜電潛像變?yōu)榭?首先碳粉被吸引到磁轆農(nóng)面。粉刀的控制下，在磁輪表面形成一特定厚 均勻碳粉層，并通過磨擦使碳粉帶電。再 AC/DC偏壓作用，使碳粉在磁餛表而震動 轉(zhuǎn)移到OPC上。OPC上的潛像區(qū)吸引碳粉 面形成可見的碳粉圖像。Developing is to convert the electric latent image into visible toner image a

Toner is attracted onto the mag sleeve nlagnetically from the toner hoppenand charge via friction between the mag sleeve and the de blade.The doctor blade also evenly meters the toner amount on the mag SLEEVE.An AC/DCvoltage give the toner a negative charge bias transfers th
