摘要： A laser beam printer is provided which is capable of compensating for the difference in diameter between dots every colors and preventing unintentional coloring of the boundary between colors. In a conventional light source used for a printer, a spot diameter thereof is small upon low output and large upon high output. However, in a semiconductor laser device of the present invention, which is used for a light source for a printer, the spot diameter of the light source is controlled so as to be large upon low output and small upon high output. It is thus possible to keep the spot diameter of the laser light source constant. As a result, an irregular color-free laser beam printer can be materialized.

摘要： A high-speed image forming method and apparatus is capable of directly controlling a toner by the force of an energy beam. Selected toner particles in a mass of toner adhering to the surface of a transparent drum are irradiated with a laser beam emitted by a laser disposed within the transparent drum and controlled for scanning according to image information. The laser beam separates the selected toner particles from the transparent drum by the force it produces on the particles, and then the separated toner particles are moved to a paper sheet by the force of an electric field produced by a developing electrode. Each toner particle need only be irradiated with the light for a comparatively short period of time, so that an image can be formed at high speed.

摘要： A laser printer can record high definition and high quality images without requiring any increase of electrical and mechanical design precision for increasing a scanning line density thereof. The laser beam is deflected in a primary scanning direction and a subsidiary scanning direction. With such scanning, an artificial scanning line along an edge of a recording image can be established for accurately recording an oblique line, a curved line, a barbel portion of a character, a half-tone image or so forth.

摘要： An optical arrangement for an optical scanning apparatus which can record a plurality of high precision information concurrently, provides for a laser beam emitted from a single light source to be polarized in two polarization directions, and each of the two polarized beams is further imparted with different information according to its polarization direction. Then, the two polarized beams are used for scanning over a photosensitive member to concurrently record respective information at different positions on the photosensitive member. In order to suppress induced light fluctuation depending on an incident angle of light on the beam splitter, an optical rotation means is provided in the optical system, such that a desired optical rotation control can be obtained corresponding to the incident angle on the beam splitter, so as to compensate for the fluctuation of light whereby the beam splitter can be arranged to be free of the influence of the incidence angle of the beam.
