    Abstract: An image forming apparatus is disclosed. The image forming apparatus executes operations of idle ink ejection in which ink droplets not contributing to forming an image on a recording medium are ejected. When the operations of the idle ink ejection are executed before staring to print an image on a recording medium, the ink droplets are ejected into a cap member; in a case where the operations of the idle ink ejection are executed when a first predetermined period has passed after the last ejection of the ink droplets from the recording head, the ink droplets are ejected into an idle ink droplet receiving section; and in a case where the operations of the idle ink ejection are executed when a second predetermined period longer than the first predetermined period has passed as one of cleaning operations of the recording head, the ink droplets are ejected into the cap member.
