摘要： A developing apparatus includes a rotatable photosensitive drum having a peripheral surface carrying an electrostatic latent image to be developed. A plurality of developing rolls are disposed in opposition to the photosensitive drum, with developing gaps being formed between the developing rolls and the drum. Each of the developing rolls is constituted by a rotatable cylindrical sleeve of a non-magnetic material and a permanent magnet, stationarily disposed within the cylindrical sleeve, having a plurality of magnetic poles formed on the peripheral surface thereof. By rotating the sleeves in the same direction, developer is transferred from one to another developing roll while forming magnetic brushes which slidably contact the drum surface at the gaps. The latent image is developed by the magnetic brushes. To assure the positive transfer of developer, the magnetic poles of the adjacent developing rolls, positioned in opposition and closest to each other, are magnetized in opposite polarities and one or both of these magnetic poles are positioned, as viewed in the rotating direction of the associated sleeves, upstream of the position at which the adjacent developing rolls come closest to each other.

摘要： A developer-carrying member to be installed in an electrophotographic developing device for carrying and conveying a developer along a surface thereof, is formed of a substrate, and an intermediate electroless plating layer and an electroplating layer disposed in this order on the substrate. As a result of the electroless and electro double plating layer structure, the developer-carrying member is provided with a wear-resistant surface which has an appropriate degree of roughness suitable for conveying the developer thereon and is yet free from minute projections and cracks undesirable from the viewpoint of continuous image forming performances.

摘要： A heat-fixing device for heating a toner image on a sheet-like member includes a rotatable heating roller for heating the sheet and a rotatable pressing roller for pressing the sheet-like member against the heating roller, the longitudinal axis of one of the heating roller and the pressing roller being fixed to a frame and the longitudinal axis of the other roller being not fixed to the frame. A guide arm swingable on a swing axis fixed to the frame and supporting the other roller is provided at a position distant from the swing axis to guide the movement of the other roller in relation to the fixed roller, and a moving arm and an elastic element arranged between the guide arm and the moving arm are also provided so that the moving arm drives the guide arm through the elastic element to press the sheet-like member between the heating roller and the pressing roller. An internal groove-cam follower surface in the moving arm enables the pressing force between the heating roller and the pressing roller to be adjusted in accordance with a movement of the moving arm when the pressing roller and the heating roller are in contact with each other.
