In storage portion, print data received from outside is stored. Counting portion counts an elapsed time period from a time of reception of the print data. Operation input portion receives an operation input for issuing a printing instruction for the print data stored in storage portion. Return portion compares a counted value obtained by counting portion with a first set time period set based on a printing standby time period from a time of reception of the print data until a time of inputting of the printing instruction via operation input portion, and cancels a power saving operation state of the image forming apparatus to cause the image forming apparatus to return to a normal operation state when the counted value has become the first set time period.
