发明名称 Image forming apparatus
摘要 An image forming apparatus includes an apparatus body, an image bearing member, and a development cartridge which has a developer bearing member that is detachable and attachable against the apparatus body. In addition, a supply portion supplies a developer to the development cartridge and is configured to connect and separate from the development cartridge in the apparatus body in the vertical direction, and a movement mechanism moves the development cartridge away from a surface of the image bearing member by supporting the development cartridge and moving it from an attached position in a substantially vertical direction. A seal portion is configured around a connecting portion between the supply portion and the development cartridge and can seal the connecting portion by compressing with movement of the development cartridge by the movement mechanism.

主权项 1. An image forming apparatus comprising: an apparatus body; an image bearing member on which a latent image is formed; a developing device provided detachably attachable to the apparatus body, configured to develop the latent image formed on the image bearing member, the developing device includes a developer bearing member bearing a developer and conveying the developer to a development position opposing the image bearing member and a receiving port for receiving the developer, wherein a line linked between a center of the developer bearing member and a center of the image bearing member slants against a horizontal plane in view from an axial direction of the image bearing member when the developing device is positioned at a set position where the developing device is to be set; a supply device configured to supply the developer to the developing device positioned at the set position through a supply port provided in the supply device, wherein the receiving port is arranged under the supply port and capable of receiving the toner dropped from the supply port when the developing device is positioned at the set position; and a movement mechanism configured to move the developing device between the set position and a separate position where the developing device is away from the image bearing member, wherein the movement mechanism moves the developing device from the set position to the separate position vertically so as to separate the developing device from the supply device.
