Abstract: An image forming apparatus includes: a correction content extractor that compares original image data of an original image formed on an image-formed recording material, with corrected original image data of the original image that is corrected, and extracts a correction content of the original image; a correction position extractor that compares the original image data with read image data read from the image-formed recording material, and extracts a correction position of the correction content according to a shape of the image-formed recording material; a correction image data generator that generates correction image data for forming a correction image in accordance with a shape of the image-formed recording material based on the correction content and the correction position; and an image former that forms the correction image at the correction position of the image-formed recording material based on the correction image data.

Abstract: A tandem type image forming system includes a first image forming apparatus, and a second image forming apparatus connected in series to the first image forming apparatus and located on a downstream side in a sheet conveyance direction with respect to the first image forming apparatus. The tandem type image forming system has a controller which shortens a second sheet interval when conveying a plurality of consecutive sheets from the first image forming apparatus to the second image forming apparatus than a first sheet interval when conveying the plurality of consecutive sheets from the second image forming apparatus to a post processing apparatus connected to the second image forming apparatus.

Abstract: An image forming device includes: an image forming unit configured to form a plurality of images on continuous paper based on a job; an image pattern creation unit configured to interrupt execution of the job and create an image pattern for consuming toner; a determination unit configured to determine necessity of creating the image pattern based on coverages of the images included in the job; and a calculation unit configured to, when the determination unit determines that it is necessary to create the image pattern, calculate a conveyance distance or a conveyance time of the continuous paper until creation of the image pattern, as interruption timing.

Abstract: Disclosed is an image forming system, which makes it possible to effectively eject the jam-subsequent paper sheet remaining therein. In the system, a primary abnormal state in which the conveyance operation cannot be continued, and a secondary abnormal state in which an adverse influence is possibly incurred to the image formed on the paper sheet though it is possible to continue the conveyance operation, are defined. In the state that the primary abnormal state or the secondary abnormal state is detected in midcourse of the conveyance operation, when a pre-purge processing for conveying the jam-subsequent paper sheet is implemented so as to eject the jam-subsequent paper sheet onto the ejecting tray, controlling operations are conducted so as to continue the conveyance operation without halting the conveyance operation, even if the secondary abnormal state in respect to the jam-subsequent paper sheet is detected in midcourse of performing the pre-purge processing thereof.
