An image forming apparatus includes a job memory which stores each of image formation jobs, which are received from terminals, in association with a user identifier which identifies a user of a corresponding terminal, an image forming unit which executes the image formation jobs which are stored in the job memory, a user detector which detects a user identifier of each approaching user, and a controller which calculates, upon detection of plural user identifiers by the user detector, elapsed times from reception times of image formation jobs which are stored in the job memory in association with the user identifiers, compares the elapsed times, and controls the image forming unit to preferentially execute the image formation job with a shortest one of the elapsed times.
