An image forming device includes an operation unit, a job executing unit, a receiving unit, a first determining unit, and a second determining unit. The print job received at the receiving unit contains information about an amount of print resource to be consumed. The first determining unit determines whether the receiving unit receives a print job while the user is setting another print job by the operation unit. The second determining unit determines whether the print resource remains as much as both the received print job and the another print job can be executed when the first determining unit determines that the receiving unit receives the print job while the user is setting the another print job by the operation unit. The job executing unit sets an order of priority for executing the print job based on the determination result of the second determining unit.
