摘要 |
A developer includes a developer frame in which a developing agent is contained, a development roller that is rotatably disposed inside the developer frame. Coupling means couples the development roller to the developer frame. The coupling means includes a gear member that is rotatably mounted to the developer frame and engages a first gear disposed outside the developer to transfer a rotational force. A development roller end portion rotates with the gear member in the same direction about the same rotational shaft as the gear member. An image forming apparatus includes a photosensitive medium on which an electrostatic latent image corresponding to an image to be printed is formed through light scanning and the developer, which applies a developing agent to the photosensitive medium to develop the image into a visible image.
