An image forming apparatus includes a controller and a reservation job managing unit. The controller is configured to perform a print job or a transmission job using a printing device or a communication device. The reservation job managing unit is configured to (a) register schedule data and job data of a reservation job that is a print job or a transmission job in a predetermined storage device, (b) determine whether the job data is stored in the storage device or not when a reservation time has come on the basis of the schedule data, and (c) notify a user of that the job data is not stored in the storage device if the job data is not stored in the storage device, and afterward cause the controller to perform the reservation job if the job data is restored in the storage device.
