Electrophotography is the technology used in laser printing which transfer data representing texts
or graphics objects into a visible image which is developed on the photosensitive drum, finally
fusing on paper, using light beam generated by a laser diode.
This section provides technical details on the printer’s electrophotography system.
4-1-1 Electrophotographic cycle
The electrophotography system of the printer performs a cyclic action made of six steps as follows.
Each step is technically explained in the following sections.
