摘要： According to this invention, optical the path lengths from two semiconductor laser oscillators to a photosensitive body are different from each other. Oscillation is switched between the two semiconductor laser oscillators to change the beam shape of a laser beam on the photosensitive body. Since the beam shape of the laser beam can be controlled at accurate timings, a good image can be obtained, and a thin line and a high quality gradation image can be reproduced on a single image. An image having no gradation levels and an image having gradation levels can be simultaneously formed both with high quality.

摘要： In a housing in which a printing unit is provided, a printed-paper storing unit that stores paper printed by the printing unit is provided to be removable to the outside. This printed-paper storing unit can be brought into a lock state in which removal to the outside of the housing is physically prevented by a fixing mechanism. When a print job sent from a user side designates internal storage of printed paper, the printed-paper storing unit is fixed in the housing by the fixing mechanism and locked. An unlock number of a number selected at random is notified to the user side to perform printing. After the printing is finished, the finish of the printing is notified to the user side and the lock state is released according to input of the unlock number to make it possible to remove printed paper to the outside.
