Abstract
An image formation apparatus for performing a gradation recording by changing a size of a dot on the basis of an image data inputted to the apparatus. The apparatus divides an image into a plurality of blocks each comprising a predetermined number of pixels and gives a preferential order with respect to a position within each of the plurality of divided blocks. When the preferential order is higher, the size of the corresponding dot is first enlarged on the basis of a density of the image data. This arrangement can prevent generation of a texture and deterioration of the image resolution irrespective of the case that characters or line drawings are mixed with half-tone pictures in the image.
