摘要：
In a printing apparatus, there are provided a transfer drum having a charge storage layer and an electrode provided on one side thereof, a printing head having a photoconductive layer provided at the other side thereof, a transparent electrode provided on the photoconductive layer such that the photoconductive layer and the charge storage layer are interposed between the transparent electrode and the electrode, a beam applying device for applying a constant laser beam to the photoconductive layer from a side of the transparent electrode, a printing signal applying device for applying a printing signal between the transparent electrode and the electrode, developing device for developing the charge pattern, and photographic fixing device for fixing the developed charge pattern on a piece of paper. Since the charge storage layer on a transfer drum is provided apart from the photoconductive layer, the laser printer has a simple structure, and can be presented with low cost.
