摘要： Image fixing device for use in electrophotographic apparatus, capable of suppressing gloss of fixed toner image, thus stably producing images of high quality and high level of fixing intensity over a long period of time. The fixing device is composed of a belt-type heating member and a pressing roller which are contacted with each other and rotate to form therebetween a nip through which a paper supporting unfixed toner image is passed to have the toner image fixed to the paper. The belt-type heating member comprises a metallic endless belt having fine irregularities formed on its surface and a surface layer made of a resin. The surface roughness of the fine irregularities ranges between 10 and 45 .mu.m, when measured by a ten-point averaging method.

摘要： A uniform image is obtained by matching the sliding friction force, the moving speed and the developing agent in a developing region of two developing rollers and an electric characteristic of a photosensitive body used for image development. Two developing rollers rotating in directions opposite to each other are used, the moving direction of the first developing roller being opposite to the moving direction of the photosensitive body, and a circumferential speed ratio of a circumferential speed of the first developing roller to a circumferential speed of the photosensitive body is within a rage of 0.5 to 2.5; and the moving direction of the second developing roller is equal to the moving direction of the photosensitive body, and a circumferential speed ratio of a circumferential speed of the second developing roller to a circumferential speed of the photosensitive body is within a range of 1.5 to 3.5. A ratio of the sliding friction force between a magnetic brush for developing agent and the photosensitive body formed in the first developing roller and the sliding friction force between a magnetic brush for developing agent and the photosensitive body formed in the second developing roller is within a range of 0.9 to 2.1.

摘要： A cooling device used in an electrophotographic image forming device includes a cooling roller, which is a heat roller, and a backup roller pressed against the cooling roller to form a nip portion therebetween. After being discharged from a fixing device that thermally fixes a toner image onto a recording sheet, the recording sheet passes through the nip portion, whereby the cooling roller cools the recording sheet. The cooling roller is maintained at 100° C. or higher.
