ABSTRACT:
An image formation apparatus has a photosensitive drum or photosensitive paper sheet for forming a dot image thereon, a printer head having an LED array, and LED drive ICs for selectively driving the LEDs. Dot width in the subscanning direction is properly controlled to form an excellent pseudo halftone image. A cylindrical lens or the like can be inserted between the LED array and the drum so as to prevent formation of black or white stripes in white or black image portions.
