Abstract:
An image forming apparatus includes a recording head for discharging an ink droplet onto a recording medium in a print operation; a maintenance operation unit performing a primary maintenance operation on the recording head after a predetermined time following completion of the print operation; a standing time calculation unit calculating a standing time between a completion time of a secondary maintenance operation performed in the predetermined time and an end time of the predetermined time; an intensity comparing unit comparing an intensity of the primary maintenance operation and an intensity of the secondary maintenance operation; and a selection unit selecting a type of the primary maintenance operation based on the standing time when the intensity of the secondary maintenance operation is greater than the intensity of the primary maintenance operation.
