とするレーザビームプリンタ。 In a laser beam printer in which a laser beam is reflected by a rotating polygon mirror to form an electrostatic latent image on the surface of a photoreceptor, the polygon mirror is placed on the optical path of the laser beam between the polygon mirror and the photoreceptor. A laser beam printer characterized in that a prism is provided that rotates in conjunction with rotation, and the linear velocity of the laser beam that scans the surface of the photoreceptor is kept constant.
