れた感光ドラム（Ｃ）面上には潜像が形成される。(Prior Art) Recently, an optical deflection device has been introduced as a central mechanism in an electrophotographic transfer type printer (laser printer) that prints characters and symbols using a laser beam. FIG. 6 shows a laser printer whose main components include a semiconductor laser device f (A), a light polarizer (B), and a photosensitive drum (C). Thus, the laser beam irradiated from the semiconductor laser device (A) is converged by the first optical system (D) and projected onto the converter (E). Then, the laser beam of this modulator (E) undergoes light intensity modulation in accordance with the electrical signal applied to this modulator (E). Next, the laser beam modulated by the modulator (E) enters the polyhedral mirror (G) of the optical photometer (B) via the second optical system (F). At this time, when the polygon mirror (G) is rotated at a constant speed in the direction of the arrow (R1), the laser beam is reflected and deflected by the polygon mirror (G),
The surface of the photosensitive drum (C) rotating at a constant speed in the direction of the arrow (R2) is scanned through the third optical system (H), and a latent image is formed on the scanned surface of the photosensitive drum (C). It is formed.
