  • Publication number: 20090123168
    Abstract: An image forming apparatus includes an image carrier for carrying a toner image and a transfer device. In the transfer device, a voltage applier applies a predetermined voltage to a transfer electric field generator. A potential measurement device measures a surface potential of the transfer electric field generator when a predetermined time period elapses after the voltage applier applies the predetermined voltage to the transfer electric field generator. A controller determines a transfer bias to be applied by at least one transfer member to the transfer electric field generator based on the measured surface potential of the transfer electric field generator. The at least one transfer member applies the transfer bias to the transfer electric field generator to generate a transfer electric field. The toner image is transferred from the image carrier onto a toner image receiver by the transfer electric field generated by the transfer electric field generator.
