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.

Abstract: An image forming apparatus includes an image forming device, a belt member, a reflection-type photosensor, and a reflection member. The belt member includes plural suction holes to attract a printing medium onto the belt member. The reflection member reflects light from the reflection-type photosensor through the suction holes. The reflection member is disposed inside the belt member. The reflection member has a reflection rate at which, when the reflection-type photosensor receives reflection light at positions of the suction holes with a transparent printing medium being not present on the belt member, a sensor output of the reflection-type photosensor is lower than a predetermined reference value, and when the reflection-type photosensor receives reflection light at the positions of the suction holes with the transparent printing medium being present on the belt member, a sensor output of the reflection-type photosensor is equal to or greater than the predetermined reference value.

Abstract: An image forming apparatus includes an image forming device, a conveyance unit, a correction unit, and an attitude controller. The image forming device forms an image on a printing medium. The conveyance unit is disposed opposing the image forming device to convey the printing medium. The correction unit corrects an attitude of a leading edge of the printing medium sent out from the conveyance unit. The attitude controller controls correction of the attitude of the leading edge of the punting medium performed by the correction unit. The attitude controller determines whether or not the correction of the attitude of the leading edge of the printing medium is to be performed, and causes the correction unit to perform the correction when the attitude controller determines that the correction is to be performed.

Abstract: A liquid ejector includes a head having a plurality of nozzles arranged along a first direction of a nozzle surface of the head to eject a droplet from the nozzles, and an ejection detector to detect whether or not a droplet is ejected from the plurality of nozzles of the head by detecting an electrical change generated when the droplet lands onto the ejection detector. The ejection detector includes a droplet landing surface arranged opposed to the nozzle surface, a wiper to wipe the droplet off the droplet landing surface along the first direction, and a cleaner having a contact surface to remove the droplet adhered to the wiper after the wiper wipes the droplet landing surface. The contact surface has a curvature such that side ends of the wiper contacts with the contact surface at first, and then a center part of the wiper contacts the contact surface.
