Abstract
In an image forming apparatus, an image forming section forms an entire object image using at least two dot-sequence forming units. At that time, at least two image quality control sections corresponding to the respective dot-sequence forming units control an actual-image forming state of each of dots of the object image. A buffer section has a predetermined number of line-data buffers each for storing the line data of an individual line of image data received from the image-forming request source for temporary retention and is shared by the plural image quality control sections. In the meantime a data-store-and-read control section controls a data store operation and a data readout operation so as to execute the two operations in parallel. Because possible duplicated line data is treated in an efficient way to minimize transmission of useless line data, it is possible to reduce the number of line-data buffers to a minimum, thus resulting in a simplified apparatus construction and a reduced cost manufacturing cost.
