  • Patent number: 8121506
    Abstract: An image forming apparatus includes: an image carrier that carries a developed image that has been developed on a surface thereof using a developer; a transfer member that transfers the developed image from the image carrier to a belt-shaped member; an electric power supply unit that supplies electric power to the transfer member; a measurement unit that measures a combined resistance value of the image carrier, the belt-shaped member, and the transfer member; and a controller that controls the electric power supply unit. The controller controls the electric power supply unit such that the electric power supplied to the transfer member is changed from a predetermined first supply value to a second supply value, the second supply value being larger than the first supply value, when the combined resistance value measured by the measurement unit is lower than a predetermined combined resistance value.

  • Patent number: 8120812
    Abstract: A method for maintaining color consistency in an environment of networked devices is disclosed. The method involves identifying a group of devices to which a job is intended to be rendered; obtaining color characteristics from devices in the identified group; modifying the job based on the obtained color characteristics; and rendering the job on one or more of the devices. Modifications are computed by a transform determined by using the color characteristics of the output devices along with the content of the job itself. The method further maps colors in the original job to the output devices' common gamut, i.e., intersection of the gamuts of the individual printers wherein the color gamut of each device is obtained from a device characterization profile either by retrieving the gamut tag or by derivation using the characterization data in the profile.
