Abstract: An inkjet recording apparatus includes a recording head, a conveyance belt, a control portion, an ink collector, and a suction portion. The ink collector includes a plurality of ink receivers that receives ink that has passed through openings of the conveyance belt during execution of flushing, a waste ink tank disposed below the ink receivers, a suction path that is formed in the waste ink tank and leads from each of the ink receivers to the suction portion, and an ink absorber that is filled in the waste ink tank and absorbs the ink sucked from the ink receivers. The suction path is formed by void spaces surrounded by the ink absorber.

Abstract: Provided is an ink-replacement method for an inkjet recording apparatus that includes a recording head having an ink ejection surface on which a plurality of nozzles for ejecting ink onto a recording medium is arranged, a sub-tank for temporarily retaining the ink supplied from an ink container, and an ink flow path along which the ink circulates from and to the sub-tank by passing through the recording head. In replacing a first ink present in the ink flow path with a second ink to be newly supplied to the recording head via the ink flow path, when the second ink is caused to flow from the sub-tank into the ink flow path, pulsation is generated in the ink flow path.

Abstract: An inkjet recording apparatus includes a recording head including a plurality of nozzles for ejecting ink, a conveyor belt that has a plurality of apertures and conveys recording media one by one, a control unit, an ink receiver, and a pipe-shaped ink discharge flow path. The control unit controls drive of the recording head and the conveyor belt to perform flushing, in which the ink is ejected from the nozzle of the recording head to pass through one of the apertures, at a timing different from a timing contributing to image recording. The ink receiver is disposed to face the recording head sandwiching the conveyor belt therebetween, to receive the ink after passing through the aperture when the flushing is performed. The ink discharge flow path is connected to the ink receiver. When the flushing is performed, a predetermined amount of liquid is stored in the ink receiver.

Abstract: An ink jet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, and a controller. The recording head includes an ink ejection surface having an ink ejection port from which ink is ejected. The cleaning liquid supply device includes a cleaning liquid supply surface having a cleaning liquid supply port from which cleaning liquid for wiping the ink ejection surface with the wiper member is supplied, and is located upstream of the ink ejection surface in a wiping direction. The controller controls a cleaning operation including squeezing out the cleaning liquid containing bubbles from the cleaning liquid supply port, and moving the wiper member carrying the cleaning liquid containing bubbles, in the wiping direction from a movement start position to an end position ahead of the ink ejection surface.

Abstract: A developing device of the present disclosure includes a developing roller, a toner supplying roller, a regulation blade, a casing, a toner receiver support member, a toner receiver member, and a vibration generator. The toner receiver support member is disposed inside the casing so as to face the developing roller or the toner supplying roller between the regulation blade and an image carrier. The toner receiver member is disposed along a longitudinal direction of the toner receiver support member, and has a toner receiving surface that receives toner falling from the developing roller. The vibration generator vibrates the toner receiver member. At each end part of the toner receiving surface in its longitudinal direction, there is formed a thin-walled portion that is thinner in thickness than other parts of the toner receiving surface.

Abstract: A recovery system for a recording head according to the present disclosure includes a wiper, a drive mechanism, and a control portion. The control portion is able to execute a recovery operation for the recording head that includes an ink pushing-out operation that forcibly pushes out ink, a first wiping operation that moves the wiper in a first direction to wipe away purged ink, and a second wiping operation that moves the wiper in a direction opposite to the first direction to wipe away remaining ink. The wiper includes a first wiping surface disposed to face in the first direction, a second wiping surface disposed to face in a direction opposite to the first direction, and an upper surface. The first wiping surface and the upper surface have a high water repellency compared with the second wiping surface.

Abstract: In an inkjet recording apparatus, when one set of image data is divided in the sub scanning direction into A bands, and nozzles are divided in the main scanning direction into groups each comprising A nozzles, a selector associates, within each of the group, the nozzles in the first to Ath columns with the first to Ath bands with no overlap, and, for a nozzle that is to discharge ink for one pixel or less within one set of image data, makes the nozzle perform preparatory discharge in the band associated with the nozzle by selecting, out of different ink discharge drive waveforms, a first drive waveform (1) corresponding to the minimum gradation.
