Abstract:
An apparatus for forming an image by conveying an optical head in a main scanning direction and a sub-scanning direction relative to a photosensitive material, comprising:said optical head having a first major group of light emitting elements including a plurality of light emitting elements aligned in the sub-scanning direction, each light emitting element of the first major group of light emitting elements emitting light having a peak emission wavelength that is substantially the same as that of other light emitting elements of the first major group of light emitting elements;a conveyor which conveys the optical head in the sub-scanning direction relative to the photosensitive material and which conveys the optical head in the main-scanning direction substantially perpendicular to the sub-scanning direction relative to the photosensitive material; anda controller which controls the conveyor and the optical head such that a single pixel at a same position on the photosensitive material is exposed plural times by plural different light emitting elements of the plurality of light emitting elements aligned in the sub-scanning direction at plural different main scanning times.
