Publication number: 20090142088Abstract: An image forming apparatus of the present invention is arranged so that plural sheets of paper are conveyed to a main conveying path and a sub-conveying path at the time of double-side image formation. In performing double-side image formation jobs on plural sets of sheets of paper, a sequence control section makes a change of sequences for image formation so that a post-process for the previous job can be performed during image formation of the next set. With this, in performing double-side image formation jobs on plural sets of sheets of paper in an image forming system constituted by an image forming apparatus and a post-processing apparatus, images can be formed in succession without suspending image formation of the next set to allow post-processing time for the previous set. This makes it possible to achieve a system with high job efficiency.Type: ApplicationFiled: December 3, 2008Publication date: June 4, 2009Applicant: Sharp Kabushiki KaishaInventor: Kenji Tanaka
