Abstract: An inkjet recording apparatus includes a recording head, a conveyance belt, a control portion, an ink receiver, an ink discharging flow path, and a liquid supply mechanism. The recording head includes a plurality of nozzles for ejecting ink. The conveyance belt has a plurality of first openings and conveys a recording medium. The control portion executes flushing in which the ink is ejected through the nozzles of the recording head to pass through any of the plurality of first openings. The ink receiver is opposite disposed to be opposed to the recording head via the conveyance belt and receives the ink that has passed through the first openings during execution of the flushing. The ink discharging flow path is connected to the ink receiver. The liquid supply mechanism supplies a liquid capable of dissolving the ink into the ink receiver.

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: 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: An inkjet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, a cleaning liquid flow path, and a controller. The cleaning liquid flow path includes a vertical tubular member connected to the cleaning liquid supply device and extending upward, and a horizontal tubular member connected to an upper end of the vertical tubular member and extending in a horizontal direction. The controller extrudes a cleaning liquid in at least a part of the cleaning liquid flow path from a cleaning liquid supply port before control of a cleaning operation for wiping an ink ejection surface of the recording head, thereby performing control of an air bubble release operation of the cleaning liquid flow path.

Abstract: A developing device includes a housing, a development roller, and a roller gear. The roller gear is disposed at one axial end of the development roller and transmits a rotational drive force to the development roller. The development roller includes a sleeve and a coating layer. The coating layer is formed by dipping the sleeve in a dipping bath with the sleeve directed axially vertically. The development roller is mounted to the housing such that a lower axial end of the development roller at the time of the dipping is an opposite axial end to the one axial end at which the roller gear is disposed.
