  • Patent number: 8998369
    Abstract: An image forming apparatus is provided with a conveyance belt, image forming portion, belt moving mechanism, optical sensor, current generation portion, position detection portion, belt movement control unit, reference value storage portion, base current measurement portion, initial value storage portion, and correction value determination portion. The current value measurement portion monitors the decrease in the value of a light receiving signal while decreasing an electric current generated in the current generation portion, and, in the case where the value of the light receiving signal reaches a reference value stored in the reference value storage portion, measures the value of a base current that is generated by the current generation portion. The correction value determination portion determines a correction value of a light emitting current, so that the value of the light emitting current increases depending on the amount by which the base current increases relative to an initial value.

  • Patent number: 8186823
    Abstract: An inkjet recording method including: (i) exposing a surface of a recording medium to non-thermal atmospheric pressure plasma so as to hydrophilize the surface of the recording medium, and (ii) applying a stimulus to an ink composition so as to eject the ink composition to form an image on the recording medium, wherein the ink composition contains at least one of a pigment/water-dispersible resin particle mixture in which a pigment is dispersed along with water-dispersible resin particles and colored water-dispersible resin particles each of which is a water-dispersible resin particle which is colored.
