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 feeding unit of an image forming apparatus, which includes: a pickup roller; a first feed roller to feed the paper in a required direction; and a reverse roller to prevent a plurality of sheets of paper from being fed by rotating in an opposite direction to the first feed roller and to separate the paper into individual sheets, wherein the first feed roller has a contact section in contact with the reverse roller and a non-contact section where the first feed roller is apart from the reverse roller and the first feed roller feeds the paper by making a one-time rotation and stops rotating with the non-contact section facing the reverse roller. Since the feed roller and the reverse roller are put apart from each other in a waiting mode, the rollers can be protected from abrasion and paper can be fed smoothly.
