  • Patent number: 9274483
    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.

  • Patent number: 9244386
    Abstract: A developing device includes a first developer holder and a second developer holder. The first developer holder is disposed so as to face an image holding member and rotates so as to move in a direction opposite to a direction of movement of the image holding member at a first facing portion. The second developer holder is disposed downstream from the first developer holder in the direction of movement of the image holding member so as to face the image holding member and rotates so as to move in the same direction as the image holding member moves at a second facing portion. A value obtained by dividing an amount of developer per unit area held on the first developer holder by a shortest distance between the image holding member and the first developer holder is approximately in a range from 1.00×103 kg/m3 to 1.60×103 kg/m3.

  • Patent number: 9164436
    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.
