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： The rectangular planar-type ICP (Inductively Coupled Plasma) antenna having a balanced ratio of a magnetic field and an electric potential is capable of improving uniformity of plasma as well as improving a density of plasma. The planar-type ICP antenna includes first and second antenna elements spirally shaped outwards from an end thereof, respectively. The ends of the fist and second antenna elements are interconnected by means of a grounded common terminal. A RF power source is connected to a powered common terminal for connecting first and second powered terminals that are the other ends of the first and second antenna elements. The first and second powered terminals are arranged in peripheral portions of the antenna and the grounded common terminal is arranged in a center portion of the antenna in order to compensate for a drop of plasma ion flux in a region to which power is applied.
