ABSTRACT:
An image forming apparatus has a liquid discharge head to discharge droplets of a recording liquid to form an image on a recording medium and a maintenance-and-recovery mechanism to perform a maintenance and recovery operation on the liquid discharge head. The maintenance-and-recovery mechanism includes a suction device, a control unit, a drain tube, and a drain reservoir. The suction device suctions droplets of the recording liquid from the liquid discharge head. The suctioned droplets are not used for an image forming operation. The control unit controls a suction speed of the suction device. The drain reservoir stores the suctioned droplets drained from the drain tube. The drain tube is inclined relative to an opening portion of the drain reservoir. The control unit controls the suction speed of the suction device to change a drain speed of the suctioned droplets drained from the drain tube.
