Patent number: 10320999Abstract: An image forming apparatus includes circuitry configured to receive a first print job and ejection-destination designating information designating one of a plurality of ejection destinations as an ejection destination of a first printed matter based on the first print job. The circuitry is configured to perform, based on the ejection-destination designating information, a determination of whether to eject the first printed matter to a previous ejection destination to which a second printed matter has been ejected based on a second print job received one before the first print job. The circuitry is configured to select the ejection destination of the first printed matter according to the determination.Type: GrantFiled: April 24, 2018Date of Patent: June 11, 2019Assignee: Ricoh Company, Ltd.Inventor: Masashi Taniguchi
