摘要： 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.

摘要： An ink container includes a liquid storing container and a container case. The liquid storing container is filled with an ink and provided with a spout discharging the ink at one end side. The container case contains the liquid storing container and fixes one end of the liquid storing container. The ink storing container contracts and lengthens in forward and backward directions in accordance with reduction in the ink from a state where the ink is filled inside. The container case includes a first housing part and a second housing part. The first housing part houses the liquid storing container in an ink filled state. The second housing part has the height dimension smaller than the height dimension of the first housing part and houses a lengthened amount of the liquid storing container at another end side of the first housing part depending on the reduction in the ink.

摘要： An image forming apparatus has a developer container removably connected thereto, a developer feeding mechanism, a drive mechanism, and a torque limiter. The developer container includes a cylindrical container body having a developer discharge port, and a shutter fitted to be rotatable to open and close the developer discharge port. When the drive mechanism rotates the developer container in the developer feeding direction, while the torque limiter keeps the shutter stationary, the container body rotates through a predetermined angle to open the developer discharge port, and as the developer container continues to be rotated, the developer is fed through the developer discharge port. When the developer container is rotated in the direction reverse to the developer feeding direction, while the torque limiter keeps the shutter stationary, the container body rotates through a predetermined angle in the reverse direction to close the developer discharge port.

摘要： An ink-jet recording apparatus includes a sub tank that pools an ink supplied from a container, a recording head, a heater, a temperature sensor, and a control unit that supplies the ink from the container to the sub tank when an allowed state has been established. The control unit determines that the allowed state has been established when the temperature of the sub tank is equal to or higher than a tank control temperature. The sub tank has a capacity that is higher than the capacity per container.

摘要： In an inkjet recording apparatus, a recording head has an ink ejection port through which ink is ejected, a cleaning liquid supplying portion has a cleaning liquid supply port through which cleaning liquid for cleaning an ink ejection surface having the ink ejection port, is supplied, and a cleaning member cleans the ink ejection surface by the cleaning liquid by moving while in contact with the ink ejection surface. The cleaning liquid supplying portion includes a main body portion and a protruding portion. The main body portion is disposed on an upstream side of the recording head in a moving direction of the cleaning member. The protruding portion protrudes from the main body portion toward a downstream in the moving direction, and covers, from below, lower ends of side surfaces of the recording head and the main body portion that face each other in the moving direction.

摘要： In an inkjet recording apparatus, ink reserved in a reserve portion flows into a valve chamber through an inflow port. A first outflow port and a second outflow port are capable of flowing the ink from the valve chamber. The first valve element is preliminarily located at an opening position separated from the first outflow port in an inward direction directed from the first outflow port toward inside of the valve chamber. The first valve element is displaced from the opening position to the first outflow port and closes the first outflow port when the valve chamber is filled with the ink. The second valve element is preliminarily located at a closing position closing the second outflow port, and opens the second outflow port when the valve chamber is filled with the ink. Subsequently, a recording head becomes ready to record an image on a recording object with the ink.

摘要： A supply liquid tank unit of the present disclosure includes a supply liquid tank and a detection sensor. The detection sensor detects a liquid surface of ink in the supply liquid tank. The supply liquid tank is provided with an inner space having a storage chamber which stores the ink and an atmosphere release port for making an inner pressure in the inner space equal to an atmospheric pressure. The detection sensor has a float which moves vertically in accordance with an amount of the ink in the storage chamber and a sensor main body which detects a liquid surface of the ink when the float moves vertically. An inner side surface of the storage chamber is disposed along and near an outer circumferential surface of the float.
