An image forming apparatus includes an exit tray, an image forming section, a user identification section, a printed sheet receipt managing section, and a fetch sensor. The image forming section performs a printing operation based on a print instruction issued from a user. The fetch sensor is capable of detecting that a printed sheet has been fetched from the exit tray. The user identification section identifies a print requester corresponding to a user having issued a print instruction, and a fetcher corresponding to a user fetching the printed sheet from the exit tray. If the printed sheet is fetched from the exit tray and the fetcher is different from the print requester, the printed sheet receipt managing section sends, to a computer of the user, a notice of printed sheet taken away notifying that the printed sheet has been taken away.
