Abstract: The present invention provides an image processing device capable of correcting an image formation position page by page. The image processing device has: an obtaining unit obtaining a print job corresponding to a plurality of pages; a determination unit obtaining a read image of a sheet in which an image is formed for at least two pages in the plurality of pages and determining a deviation amount in the at least two pages; a calculation unit calculating at least two correction values on the basis of the deviation amount in the at least two pages; and a correction unit performing image correction on each of the plurality of pages on the basis of a corresponding correction value in the at least two correction values.

Abstract: An image-forming apparatus contains a hardware processor for forming first and second reference marks on both surfaces of a first recording medium by using respective recorder. The first reference mark includes scale marks indicating coordinates in a position range relative to a first image-forming area, and the second reference mark includes an indicator indicating a position relative to a second image-forming area. The indicator is formed in a position indicating the relative position range as seen from a direction perpendicular to the surface of the recording medium. The hardware processor is also for implementing settings for adjusting the recording action of the recorder so that positional misalignment of the first and second image-forming areas diminishes based on coordinates inputted by an input section and indicated by the indicator. The hardware processor causes respective adjusted ordinary images to be formed on both surfaces of a second recording medium by the recorder.

Abstract: Distributed printing has not been capable of being performed by flexibly correcting a printing device to which a user instructs printing. A printing management server has an information setting unit setting, to a plurality of jobs to which the user authentication information of a user is set and having relationship properties, relationship information shared among the plurality of jobs, a job delivery unit delivering the different jobs to the respective plurality of printing devices, and a distributed printing instruction unit instructing, to the printing device designated by the user, distributed printing on the basis of the job having the matched relationship information. Each of the printing devices includes a job execution unit extracting, from a storage unit, the job to which the user authentication information matched with the user authentication information authenticated as valid by an authentication unit and the matched relationship information are set, and executing the job.

Abstract: The present invention is provided with an image-forming unit for forming an image on a recording medium, and a control unit for controlling the formation by the image-forming unit of a test image used for adjustment of the image-forming unit in a blank space portion in which an image is not formed on the recording medium, the control unit specifying the size of the blank space portion, and forming a test image corresponding to the size of the blank space portion in the blank space portion. The test image is thus formed adequately utilizing the blank space of the recording medium.
