Abstract: A liquid supply unit supplies predetermined liquid from a liquid storage container storing the liquid to a liquid injection head for injecting the liquid. The liquid supply unit includes a pressure chamber, a first supply passage, a second supply passage, a bypass supply passage and a pressurizing mechanism. The pressure chamber is capable of storing the liquid. The first supply passage allows communication between the liquid storage container and the pressure chamber. The second supply passage allows communication between the liquid injection head and the pressure chamber. The bypass supply passage has an upstream end in a liquid supply direction connected to the first supply passage and a downstream end joining the second supply passage. The pressurizing mechanism is arranged in the bypass supply passage and pressurizes the liquid flowing in the bypass supply passage.

Abstract: A liquid supply unit includes a pressure chamber configured to store the liquid, a first supply passage allowing communication between a liquid storage container and the pressure chamber, a second supply passage allowing communication between a liquid injection head and the pressure chamber, and a valve mechanism configured to operate according to a pressure state of the pressure chamber. The valve mechanism prohibits the inflow of the liquid from the first supply passage in a first state where the pressure chamber is within the range of a supply negative pressure, allows the inflow of the liquid from the first supply passage in a second state where the pressure chamber is at a pressure lower than the supply negative pressure, and releases the pressure in the pressure chamber in a third state where the pressure chamber is at a pressure higher than the supply negative pressure by a predetermined value.

Abstract: A liquid supply unit includes a first chamber, a second chamber, an opening/closing member and a lever member. The first chamber communicates with a liquid storage container and is set to a first pressure. The second chamber communicates with a liquid injection head and is internally set to a second pressure decompressed from the first pressure. A posture of the opening/closing member is changed between a closing posture and an opening posture. A posture of the lever member is changed between a sealing posture for sealing an opening allowing communication between the second chamber and atmosphere and an opening posture for opening the opening. The lever member allows the opening/closing member to be set to the closing posture while being set in the sealing posture, and changes the posture of the opening/closing member from the closing posture to the opening posture while being set in the opening posture.

Abstract: A toner case includes a case main body, a feeding mechanism, a displacement member, and an elastic member. The case main body stores toner. A ventilation port is formed in the case main body. The feeding mechanism feeds the toner to outside the case main body. The displacement member includes a seal portion and is configured to be displaced between a closing position and an opening position. When the displacement member is at the closing position, the seal portion closes the ventilation port, and when the displacement member is at the opening position, the seal portion opens at least a part of the ventilation port. The elastic member holds the displacement member at the closing position by applying an elastic force to the displacement member.

Abstract: A developer storage container includes a container body, a shaft, a moving wall and a pressing member. The container body has an inner peripheral surface defining a tubular internal space extending along a first direction. The shaft is arranged to extend in the first direction in the internal space and rotatably supported. The moving wall is movable in the first direction in the internal space while conveying the developer in the internal space toward a developer discharge port. The pressing member moves integrally with the moving wall by pressing the moving wall when the shaft is rotated in a first rotating direction and relatively moves to an upstream side with respect to the moving wall according to the engagement of a first engaging portion and a second engaging portion when the shaft is rotated in a second rotating direction opposite to the first rotating direction.

Abstract: A printer 100 includes a housing, an image forming unit 120H, a body unit 150, positioning mechanisms and a lock lever 50. The positioning mechanism includes a unit biasing spring and a biasing projection, and positions the image forming unit 120H by biasing the image forming unit 120H mounted at a first position in the housing. The lock lever 50 is pivotably provided on the image forming unit 120H. The lock lever 50 can change the posture thereof between a first posture for locking the image forming unit 120H at the first position and a second posture for unlocking the image forming unit 120H and allowing the image forming unit 120H to be removed from the housing.

Abstract: A developer storage container includes a container body having a developer discharge port, a shaft body extending in a first direction and rotatably disposed in the container body, and a stirring member to be attached to the shaft body. The stirring member is made of a flexible film-like member and stirs the developer stored in the container body by rotating according to the rotation of the shaft body. The stirring member includes an attaching portion serving as an area part for attachment to the shaft body, and a stirring piece having a base portion extending from the attaching portion toward the inner peripheral surface of the container body in a second direction perpendicular to the first direction and an extending portion extending from the base portion in a third direction intersecting with the second direction to approach the developer discharge port.

Abstract: An image forming apparatus includes an apparatus main body, an image forming unit, a guiding portion, a positioning mechanism, and a posture-switchable lever member. The positioning mechanism is disposed on the guiding portion, and provided with a first urging member and a unit-abutting portion for abutting on the image forming unit. The positioning mechanism positions the image forming unit by urging the image forming unit when attached into the apparatus main body in a first position. The posture-switchable lever member is provided swingably on the image forming unit and switches between a first posture in which the posture-switchable lever member locks the image forming unit in the first position within the apparatus main body, and a second posture in which the posture-switchable lever member releases the lock on the image forming unit and permits the image forming unit to be detached from the apparatus main body along the attachment/detachment direction.

Abstract: An image forming apparatus includes an apparatus body, an image carrier, a developing device, and a developer container. The developing device includes a developer supply port and a mounting section. The developing device is mounted onto a developing position facing the image carrier through a specific insertion path in the apparatus body. The developer container includes a developer discharge port. The developer container is mounted onto the mounting section of the developing device through the insertion path. The developing device is dismounted from the apparatus body through the insertion path after being rotated from the developing position to a standby position in a first direction around a first axis extending in parallel with a rotary axis of the image carrier. The developer container is dismounted from the apparatus body after being rotated in a second direction opposite to the first direction around a second axis in the mounting section.
