Abstract: A line head includes a substrate, light emitting elements disposed on the substrate, drive circuits that drive the light emitting elements, and wirings that electrically connect the drive circuits and the light emitting elements. The light emitting elements form n (n?2) light emitting element rows. The drive circuits are electrically connected with the wirings to light emitting elements belonging to a number of light emitting element rows equal to or smaller than n?1.

Abstract: An image forming method includes: dividing input image data; transmitting first divided data to a first image processing unit; transmitting second divided data to a second image processing unit; image-processing the first divided data transmitted to the first image processing unit; image-processing the second divided data transmitted to the second image processing unit; and forming an image based on the first divided data image-processed by the first image processing unit and the second divided data image-processed by the second image processing unit.

Abstract: When image processing is performed, the present invention increases the speed of processing for an individual scanning line constituting an image, and improves the throughput while suppressing the required memory area. The present invention is an image processor for performing image processing in parallel using a plurality of processors, wherein when an individual scanning line is divided into a plurality of partial areas, at least one of the plurality of processors is allocated to each of the partial areas for at lest one scanning line constituting an image, and image processing is performed in parallel. As a memory area for storing the image processing result, the image processor comprises memory areas for the number of scanning lines, which is less than the number of the plurality of processors.
