  • Patent number: 10454988
    Abstract: A communication apparatus includes a receiver and circuitry. The receiver receives image data from a transmission apparatus. The circuitry identifies an image data type of the image data received by the receiver, and determines a transmission data capacity to be used for transmission of the image data at the transmission apparatus based on the identified image data type. The circuitry further sends a notification to the transmission apparatus, the notification requesting the transmission apparatus to transmit the image data based on the determined transmission data capacity, and outputs the image data that the transmission apparatus transmits based on the notified transmission data capacity.

  • Patent number: RE47726
    Abstract: An image forming apparatus includes a nip forming member and a transfer bias output device that outputs a transfer bias to form a transfer electric field in a transfer nip between the nip forming member and an intermediate transfer member. Upon transfer of a composite toner image including a particular toner image onto a recording medium in the transfer nip, the transfer bias output device outputs the transfer bias including a first superimposed bias in which a direct current (DC) component is superimposed on an alternating current (AC) component. Upon transfer of the composite toner image without the particular toner image onto the recording medium in the transfer nip, the transfer bias output device outputs one of the transfer bias including a second superimposed bias having a peak-to-peak value of the AC component smaller than that of the first superimposed bias and the transfer bias including only the DC component.
