Abstract: The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The suction unit causes the conveyance belt to suck the sheet. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A ratio of the recessed portions per unit area in a facing region of the conveyance plate facing the head end portion is smaller than a ratio of the recessed portions per unit area in a region other than the facing region.

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.
