摘要： An image forming apparatus is provided. The image forming apparatus includes a photoconductor, an irradiator, a developing device including a developing roller, a development bias applying device, a toner supplying roller and a supply bias applying device, and a controller. The controller changes supply bias offset by reference to at least one of five parameters including photoconductor travel distance, operation temperature of the developing device, operation humidity of the developing device, continuous operating time of the developing device, and color information of image to be produced. After changing the supply bias offset, the controller forms plural toner patterns for image density adjustment on the photoconductor by changing the development bias, and sets the development bias to a certain bias based on the image densities of the plural toner patterns so that the image produced by the developing device has a targeted image density.

摘要： 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.

摘要： A transfer device includes an image carrier that carries a toner image; a nip forming member that forms a transfer nip between the nip forming member and the image carrier by contacting with a front surface of the image carrier; and a transfer bias applying unit that applies a transfer bias, thereby transferring the toner image carried on the image carrier to a recording material at a position of the transfer nip. The transfer bias applying unit applies the transfer bias in which an AC component and a DC component are superimposed and in which a peak-to-peak voltage of the AC component is larger than 6 times an absolute value of a voltage of the DC component.
