Abstract: An inkjet recording apparatus includes an ink ejection surface, a washing liquid storage portion, a washing liquid nozzle, a mesh sheet, and a sponge member. The washing liquid storage portion includes a supply surface adjacent to the ink ejection surface. The washing liquid nozzle includes a communicating hole that is communicated from a supply port formed in the supply surface to an inside of the washing liquid storage portion, and forms a concave meniscus by a surface of the washing liquid in the communicating hole. The mesh sheet is provided in close contact with an opposite rear surface of the supply surface, and has an opening that is smaller in size than an inner diameter of the communicating hole. The sponge member is provided in a compressed state in the inside of the washing liquid storage portion, presses the mesh sheet toward the opposite rear surface of the supply 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: An ink for ink-jet recording apparatuses, includes water, a pigment dispersion, and a super-penetrating agent and a high SP organic solvent respectively having a predetermined solubility parameter (SP value). All of differences (ΔSPs) between SP values of the neighboring organic solvents are from 0.5 to 5.0 in order of SP values thereof, and the difference of SPmax−SPmin is 12 or less in which SPmax is the highest SP value of an organic solvent among organic solvents in the high SP organic solvent and SPmin is the smallest SP value of an organic solvent among organic solvents in the super-penetrating agent.
Abstract translation: 喷墨记录装置用墨水，具有分别具有规定溶解度参数（SP值）的水，颜料分散液，超渗透剂和高SP有机溶剂。 相邻有机溶剂的SP值之间的所有差异（＆Dgr; SP）以SP值的顺序为0.5至5.0，并且SPmax-SPmin的差异为12或更小，其中SPmax是有机物的最高SP值 高SP有机溶剂中有机溶剂中的溶剂和SPmin是超渗透剂中有机溶剂中有机溶剂的最小SP值。

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: 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 conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. 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 depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.
