Abstract
An image forming apparatus includes a recording head, an ejection detector, and a cleaner. The ejection detector detects ejection or non-ejection of droplets from the head and has an electrode member disposed in an area in which the electrode member is opposable to the head. The cleaner cleans the electrode member after ejection or non-ejection of droplets from nozzles of the head is detected by detection of electric changes of the electrode member generated when the droplets ejected from the nozzles land on the electrode member with a potential difference created between a nozzle face of the head and the electrode member and the nozzle face opposed to the electrode member. The cleaner includes a wiping member to wipe droplets adhering to the electrode member. The wiping member and the electrode member are configured to be relatively moved in parallel to a nozzle array direction to clean the electrode member.
