High quality images are provided without the occurrence of image quality defects due to reciprocity law failures, even when scanning a multi-beam. When interlaced scanning is employed, it is possible to select combinations such that, taking any freely selected neighboring scanning lines, respective scan numbers of the neighboring scanning lines are always different. Thus, a duration of scanning spacing can be made to be at least the duration of a single main scan. As a result, image defects such as banding due to reciprocity law failures can be greatly alleviated, and images can be provided in which image defects are to unlikely to be noticed in practice.

An A/D converter simplifies its circuit configuration without deteriorating accuracy in A/D conversion. A circuit is formed of a folding and interpolation type. A gain-variable pre-amplifier group 11 amplifies each of reference voltages Vref1 to VrefN and an analog input voltage Vin, to output the result to a folding amplifier group 12, while a gain-variable pre-amplifier group 21 amplifies each of reference voltages Vrr1 to VrrJ and the analog input voltage Vin, to output the result to a comparator group 24. Each of pre-amplifiers constituting the gain-variable pre-amplifier groups 11 and 21 has an amplification factor that varies in upper and lower comparison periods according to a clock control signal .PHI.cnt.

A light intensity control device includes light intensity balancing means for balancing the light intensities of the laser beams from the light emitting elements of the laser light source, and simultaneous operating means for simultaneously operating the light emitting elements of the laser light source, wherein the sum of the light intensities of the laser beams from the light emitting elements simultaneously operated by the simultaneous operating means is detected by single detecting means at one time, and is controlled according to the detection output from the detecting means. Accordingly, it is possible to reduce the time required to perform the control of light intensities of laser beams from semiconductor laser elements when the number of the laser beams is increased, thereby more greatly exhibiting the effect of high-speed operation obtained by the increase in number of the laser beams.
