Abstract: A printing apparatus includes a dryer unit including an intake port, a heater unit to heat outside air taken in through the intake port, an air blower unit to perform an air blowing operation, a return port to allow an inflow of part of the heated outside air blown to the print sheet, and a temperature detector unit to detect a temperature inside the dryer unit. In the air blowing operation, the returned part of the heated outside air and the outside air flow into the air blower unit. A controller unit controls the air blowing operation or the output of the heater unit.

Abstract: Recording on a recording medium with multiple types of liquid can be performed separately for a first recording unit and a second recording unit, a part of the first recording unit and a part of the second recording unit are provided at different positions in a vertical direction, and a part of a region obtained by projecting the first recording unit in the vertical direction and a part of a region obtained by projecting the second recording unit in the vertical direction overlap with each other in a horizontal direction, and the recording medium conveyed out of the first recording portion is conveyed in a horizontal attitude until the recording medium has passed a predetermined distance in a first drying portion of the first recording unit.

Abstract: A printing apparatus includes a conveying unit configured to convey a print medium with respect to a printing unit configured to eject liquid, a drying unit provided downstream of the printing unit in a first direction and configured to dry the print medium, and a control unit configured to perform control such that, in a case where the print medium is conveyed in a second direction opposite to the first direction after the image on the print medium is passed through the drying unit by conveying in the first direction, a heat transfer amount from the drying unit to the print medium is smaller than a heat transfer amount from the drying unit to the print medium in a case where the print medium is conveyed in the first direction.

Abstract: A drying unit has: a first space; a first nozzle provided in the first space; a first air blowing unit that supplies air inside of the first space to the first nozzle; a second space provided adjacent to the first space on a downstream side in a conveyance direction of the first space and communicates with the first space; a second nozzle provided in the second space; a heater that heats air inside of the second space; a second air blowing unit that supplies the heated air to the second nozzle; a third space provided adjacent to the second space; and a third air blowing unit that sucks air inside of the third space and exhausts the air to outside of the drying unit. A direction in which air is blown out from the first nozzle has a component directed toward the second space in the conveyance direction.

Abstract: Provided is an image forming unit including a photosensitive unit including an image bearing member, a developing unit including a developer bearing member and a container capable of containing a developer, a rotation shaft, the developing unit being rotated around the rotation shaft and positioned at one of a development position where the developer bearing member supplies the developer to the image bearing member and a separation position where the developer bearing member separates from the image bearing member, and a sensing portion sensing a variation or an amount corresponding to an amount of the developer contained in the developing unit. The rotation shaft is located below a developing portion, which is formed of the image bearing member and the developer bearing member, in a gravity direction.

When the developing unit is at the separation position, the sensing portion restricts the rotation of the developing unit thereby receiving a force from the developing unit.

Abstract: A developer accommodating container includes a developer accommodating portion, a stirring member, and a drive transmitting member. The developer accommodating container further includes an elastic member fixed to the stirring member at one end portion thereof and capable of expanding and contracting in a direction along a longitudinal direction of the developer accommodating portion. With respect to the longitudinal direction, the stirring member is disposed so as to form (1) a first gap between one end portion thereof and an inner surface of the developer accommodating portion on one side and (2) a second gap between the other end portion thereof and another inner surface of the developer accommodating portion on the other side. The stirring member is supported by the developer accommodating portion so as to be movable in the longitudinal direction relative to the developer accommodating portion.

Abstract: A developer container includes a developer accommodating portion, a rotatable member, and a flexible sheet member. The developer container further includes an elastically deformable elastic member. With respect to a longitudinal direction of the developer accommodating portion, between an end portion of the rotatable member and an inside surface of the developer accommodating portion, a gap is formed to permit movement of the rotatable member relative to the developer accommodating portion. In an unused state, the sheet member is elastically deformable together with the elastic member by the movement of the rotatable member relative to the developer accommodating portion in the longitudinal direction.

Abstract: A remanufacturing method for remanufacturing a second developing device from a first developing device, the first developing device including a frame provided with a developer accommodating chamber for accommodating a developer, the frame having an opening for communicating the developer accommodating chamber with the outside of the frame; and a first cap member configured to seal the opening, the first cap member being adhesively bonded to a first region of the frame with a first adhesive capable of dissolving the frame, and the remanufacturing method including: removing the first cap member from the first region such that a rough surface is formed in the first region; filling the developer accommodating chamber with the developer; and bonding a second cap member different from the first cap member to a second region of the frame different from the first region to seal the opening with the second cap member.
