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.

摘要： A paper delivery device in a printer selectively changes a stacking direction of printed and ejected paper and stacks paper. The device includes a first tray, and a second tray to pivot to a first position where paper is guided to the first tray and to a second position where the paper is stacked so that a side of an image of the paper is opposite to a side of an image of the first tray. The device also includes a first guide and a second guide to provide a side and the other side, respectively, of an ejecting route so that the paper is ejected to the first tray. The device includes a first roller and a second roller, each of the first and second rollers being installed in the first guide and second guide of the ejecting route. The device includes an ascending unit installed in the second tray to ascend the second roller so that the second roller is engaged with the first roller in the first position, and the second roller is placed under the second guide in the second position.
