Abstract: Disclosed is an image forming apparatus including a command receiving unit that receives a print command, a detector that detects a state of the operation unit, and a controller. When the detector detects that the state of the operation unit is a predetermined state subsequent to receiving the print command by the command receiving unit and prior to completion of printing based on the print command, the controller causes the printing to be terminated. When the detector detects that the state of the operation unit is not the predetermined state subsequent to receiving the print command by the command receiving unit and prior to the completion of the printing based on the print command, the controller causes the printing to be executed.
