Detailed Description
IMAGE PROCESS
Electrification
Voltage of -1650V is applied to electrification roller from HVPS and the drum surface gets electrification
of 1100V.

Exposure
Laser scanning is performed to the image printing area and the surface electric potential of scanned
area drops to about -300V to form ‘Latent Image’.
Development
Images are formed on the drum surface by attaching the electrification toner with about -600V via
development roller and Doctor blade on the latent image area formed by laser from exposure stage.

Transfer
Images are formed by tonner transfer on the drum surface from the Development stage and when paper
passes, about over +2000V electric potential applied transfer roller pulls the image forming toner
particles on drum surface to form unsettled images on the paper.
Cleaning
Remaining toner on the drum surface after transferred to paper gets trimmed by cleaning blade before
getting into electrification roller and gets collected in the used toner collecting space.
