Abstract: A fixing device includes a fixing section that includes rotatable members arranged to form a nip area through which a strip-shaped medium passes, and heaters that heat the rotatable members; and a control section. The fixing section applies heat and pressure to a toner image that is formed on the medium and passes through the nip area via the rotatable members heated by the heaters to fix the toner image onto the medium. The control section performs such control that the rotation of the rotatable members is stopped when the temperature of contact portions of the rotatable members that are in contact with the medium is lower than or equal to a first temperature that is lower than a temperature at which a portion of the medium softens.

Abstract: An image-forming apparatus includes an image unit that forms an image using at least one of a white toner and a color toner having a lower storage modulus than the white toner and a fixing unit that fixes the image to a medium with heat. A time P calculated by subtracting a fixing time for which an image of the color toner alone is fixed to normal paper used as the medium from a fixing time for which an overlaid image of the white toner and the color toner is fixed to color paper used as the medium is more than 0 ms and less than 30 ms.

Abstract: An image-forming apparatus includes an image unit that forms an image using a white toner and a color toner and a fixing unit that fixes the image to a medium with heat. The toner mass per unit area of the white toner ? (g/m2) in an image of the color toner superimposed on the white toner formed on paper used as the medium satisfies: 0.03+1.31×Rw?0.47×Rc+0.02×Gw?0.07×Gc???0.05+1.06×Rw+0.42×Rc?0.02×Gw+0.05×Gc where Rw is the average particle diameter (?m) of the white toner, Rc is the average particle diameter (?m) of the color toner, Gw is the storage modulus (kPa) of the white toner at 120° C., and Gc is the storage modulus (kPa) of the color toner at 120° C.

Abstract: An image forming apparatus includes a toner image holding member, a transfer unit, and a supply unit. The toner image holding member holds a toner image. The transfer unit transfers the toner image held by the toner image holding member to a recording medium. The supply unit supplies powder such that the powder is interposed between an end portion of the recording medium and the toner image holding member and/or the transfer unit if the recording medium includes an intermediate adhesive layer.

Abstract: An image forming apparatus includes an image forming unit and a controller. The image forming unit forms an image on a continuous recording medium by transferring to the continuous recording medium a toner image obtained by developing a latent image formed on a photoreceptor. The controller controls the image forming unit such that an image based on image information is formed in a specific image area on the continuous recording medium, and at the same time, a specific image pattern is formed in a specific side area outside the image area on the continuous recording medium.
