Image forming apparatus conducting image formation of plural jobs in parallel

摘要

An image forming apparatus includes: an image data storing device for storing an image date; an image data generating device for taking up image data from a plurality of image data sources and generating memory image data to write to the image data storing device; a writing image data generating device for generating writing image data by processing image data which have been read out from the image data storing device; an image forming device for forming an image onto a recording sheet; and a controller for controlling an entire image forming apparatus. The controller controls the writing image data generating device and the image forming device to conduct a parallel processing which forms images for a plurality of jobs in parallel.
