Abstract: An electronic device having an accessory device such as an AC adapter is constructed so that the part that holds the accessory device is not a dedicated part of the electronic device and allows the easy dissipation of heat. The electronic device has an installation member configured to attach an accessory device to the part of the electronic device that is the bottom when the electronic device is in place for use; and a support member configured discretely from the installation member, and supporting the electronic device on the installation surface when the electronic device is installed for use.

Abstract: A developing apparatus includes a first conveying member and a second conveying member shorter than the first conveying member. In a rotational direction of the rotation shaft, the second conveying member is disposed upstream of the first conveying member, with the fixed end of the second conveying member and the fixed end of the first conveying member placed one on another. The free length of the second conveying member at a first position, a second position, and a third position, which sequentially distance away from the driving transmission member in the axial direction of the rotation shaft, sequentially becomes larger.

Abstract: Disclosed is a developing apparatus including: a developer bearing member that bears a developer; a developing frame body that rotatably supports the developer bearing member; a one-end side end member that supports one-end side in an axis direction of the developer bearing member of the developing frame body; and another-end side end member that supports the other-end side in the axis direction of the developer bearing member of the developing frame body. Each of the one-end side end member and the other-end side end member is independently movable with respect to the developing frame body.

Abstract: A cartridge includes a frame and a developing roller rotatably supported by the frame. A guide member is provided at a side of the cartridge, with the guide member being rotatable between a first position relative to the frame and a second position relative to the frame. A restricting lever is movably provided between a restricting position and a non-restricting position. The restricting lever is operatively connected to the guide member such that (i) when the restricting lever is in the restricting position, movement of the guide member relative to the frame is restricted, and (ii) when the restricting lever is in the non-restricting position, movement of the guide member relative to the frame is unrestricted. The cartridge also includes a spring configured to urge the restricting lever toward the restricting position from the non-restricting position.

Abstract: A developer container includes a first sheet member installed on a rotation shaft disposed in a developer containing portion and transporting the developer to a developer carrying member, and a second sheet member installed on the rotation shaft and rotating in the same phase as the first sheet member. One end of the first sheet member and one end of the second sheet member are fixed to the rotation shaft so as to rotate in the same phase, and the other ends of the first and second sheet members are free ends. When the rotation shaft rotates in a state in which at least a part of the developer elevated by the first sheet member is positioned above the rotation shaft, the second sheet member rotates on the downstream side of the first sheet member, so as to control falling of developer on the first sheet member.

Abstract: An image forming apparatus includes a first pressing member configured to press a unit that has a second rotating member that can come into contact with a first rotating member, and a supporting member rotatably supporting the second rotating member. The first pressing member moves the supporting member so that the second rotating member moves from the contact position to the separated position. Also provided is a second pressing member that presses the supporting member. The second pressing member is capable of moving between a mounting/detaching restriction position where mounting/detaching of the cartridge to/from the apparatus main body is restricted, and a mounting/detaching allowing position where mounting/detaching of the cartridge to/from the apparatus main body is allowed.
