Abstract: An image forming apparatus is configured to change one of the expected adjustment timing and the expected switching timing so as to be matched with the other, to determine a timing for predetermined adjustment and switching of print modes.

Abstract: Provided is an image forming apparatus which acquires a plurality of jobs for repeatedly arranging images having widths smaller than a width of a continuous paper in a conveyance direction of the continuous paper, sets information for arranging the acquired jobs in a width direction of the continuous paper, forms images based on the set information, and sets a common blank forming period at which blanks among images appearing at different periods in each job coincide with each other between the jobs in the conveyance direction and forms a common blank.

Abstract: An image forming system includes an image former; a reader that executes reading a document or a sheet; a post processor that applies post processing to the document or the sheet; and a controller. The controller controls the image formation, the reading and the post processing, judges the requested degree of importance of reading for a reading target on the document or the sheet, judges existence or nonexistence of an overlap between an execution timing of the reading and a timing of generation of vibration at the post processing, judges the necessity of a countermeasure to prevent the overlap from occurring with reference to the degree of importance of reading and the existence or nonexistence of the overlap, and controls the execution timing of the reading and the post processing to prevent the overlap from occurring when the controller determines that the countermeasure is necessary.
