摘要： The quality of an image recorded on electronic paper is improved. Specifically, electronic paper for displaying an image is supplied in a region in which an electric field is generated in the thickness direction of the electronic paper, the electronic paper having charged color particles and being used for displaying an image as a result of charged color particles migrating in the thickness direction. Voltage for generating an electric field in the region is controlled by a voltage control section so that the value of the voltage varies together with time. The quality of an image recorded on electronic paper can thereby be improved.

摘要： In a fixing device incorporated in an image forming apparatus and operable to fix a toner image on a recording medium, a first rotative member and a second rotative member form a nip portion therebetween, at which the toner image is fixed on the recording medium. A separator separates the recording medium, which has been passed through the nip portion, from one of the first rotative member and the second rotative member. The separator is provided with a first guide face extending in a first direction to guide the separated recording medium to an inlet of a subsequent stage of the image forming apparatus. The first guide face is provided with a rib extending in the first direction.

摘要： A fixing apparatus, includes a fixing roller which has a middle portion and both end portions in an axis direction thereof, a pressing roller which is brought into press contact with the fixing roller for rotating so that a press contact portion is formed, an exfoliating member which exfoliates a sheet-like record medium from a surface of the fixing roller after the record medium is passed through the press contact portion, and restricting members which is provided at both end portions of the exfoliating member, and is brought into contact with the surface of the fixing roller so that an interval between the surface of the fixing roller and the exfoliating member is restricted. The middle portion of the fixing roller is smaller than the both end portions of the fixing roller in a diameter. The restricting members are brought into contact with first portions of the fixing roller other than second portions of the fixing roller in which end edge portions of the pressing roller are brought into contact with the fixing roller.
