4-1 Electrophotographic system

Electrophotography is the technology used in laser printing which transfer data representing texts
and graphics objects into a visible image which is developed on the photosensitive drum, finally
fusing them on paper using the light beam generated by a laser diode.
This section provides technical details on the printer's electrophotography system.

4-1-1 Electrophotographic cycle
