ABSTRACT:
An electrophotographic image forming apparatus includes a movable electrophotographic photosensitive member; laser beam source for providing a laser beam modulated in accordance with signals representing images to be recorded; a scanning optical system for scanningly deflecting the laser beam in a main scan direction, wherein a spot diameter (x(1/e.sup.2)), measured in the main scan detection, of a spot of the laser beam formed on the photosensitive member is not more than 45 microns, and an intensity distribution (x(1/e.sup.2)/x(1/e)) thereof in the main scan direction is not more than 1.6; a developing device for developing in a developing zone an electrostatic latent image formed by the laser beam on the photosensitive member; and supporting means for supporting the developing means to face it in the developing zone to the photosensitive member without contact thereto.
