摘要： A fixing device includes a heating roller, electromagnetic induction heater for heating the heating roller, and a pressurization roller disposed in contact with the outer periphery of the heating roller. The electromagnetic induction heater has a support extending like a tube along the outer periphery of the heating roller containing both ends in an axial direction orthogonal to a rotational direction of the heating roller and both sides parallel with the axial direction outside the heating roller. A coil is wound around the outer face of the support so as to contain a center axis of the heating roller inside the tubular part. The fixing device nips and transports recording paper to which toner has been transferred in a press contact nip part between the heating roller and the pressurization roller so as to fix an image.

摘要： An apparatus for forming a multi-color image is disclosed which includes a controller that performs an anti reverse-transfer control such that a surface potential of a previously-formed separated-developer-image subset of a plurality of single-color separated-developer-images which has been previously transferred onto an image transferred medium is reduced, prior to a subsequent transfer in which a remainder of the plurality of separated-developer-images is transferred onto the image transferred medium after a previous transfer of the previously-formed separated developer-image subset onto the image transferred medium, to thereby prevent a reverse transfer of a part of a developer material on the image transferred medium from the image transferred medium onto a photoconductor at the subsequent transfer.

摘要： A color image forming device includes a housing, a photosensitive unit, an exposing unit, at least three developing units, a transfer unit, and a fixing unit. The housing has a recording medium discharge opening for discharging recording media in a forward direction. The photosensitive unit includes a photosensitive belt with a photosensitive layer. The exposing unit exposes the photosensitive layer to form a series of latent images on the photosensitive belt. The developing units are provided in a forward portion of the housing, each including a different color developing agent for supplying developing agent to the photosensitive belt to develop corresponding latent images into visible images. The transfer unit transfers the visible images onto a recording medium. The fixing unit is provided in a rear portion of the housing unit, fixes the visible images onto the recording medium and transports the recording medium toward the discharge opening.
