Abstract:
A two-dimensional beam writing position detecting device, comprising:an optical system for scanning on a photoconductor by laser beams emitted from a semiconductor laser to form an electrostatic latent image and arranging a plurality of the laser beams in two dimensions and slantingly scanning the plurality of laser beam for forming the electrostatic latent image on the photoconductor at a predetermined angle (&thgr;); and a detector for detecting the plurality of laser beams for determining a first writing position of the plurality of laser beams on the photoconductor, wherein a longitudinal direction of a light beam receiving surface of the detecting device inclines at the substantially same angle (&thgr;1) as the slant scanning angle (&thgr;) with respect to the perpendicular of a scanning direction of the plurality of laser beams.
