摘要：
An image formation apparatus includes a writing device for selectively writing image data on a liquid crystal cell by beam light, a printer for printing out an image on a recording medium, an erasing device for erasing the image written on the liquid crystal cell by a beam of light from a specified region, and a controller for controlling the writing device for writing a novel image in the region from which the previously written image has been erased.
