Abstract
An image forming apparatus includes a recording head, an ejection detector, a cleaner and cleaning ejection controller. The ejection detector has a droplet landing member disposed in an area in which the droplet landing member faces the head. The ejection detector detects ejection or non-ejection by detecting electric change caused by landing of the droplets on the droplet landing member. The cleaner cleans a droplet landing surface of the droplet landing member. The cleaning ejection controller controls the recording head to eject droplets on the droplet landing surface for cleaning the droplet landing surface before cleaning the droplet landing surface by the cleaner. A quantity of the droplets for cleaning the droplet landing surface is greater than a quantity of the droplets for detecting ejection or non-ejection.
