Image forming apparatus including first and second bias voltage supply devices

摘要

An image forming apparatus includes a first image forming device, a plurality of second image forming devices, a first bias voltage supply device, and a second bias voltage supply device. The first image forming device and the second image forming device form a toner image. The first bias voltage supply device applies a bias voltage to a first component of the first image forming device. The second bias voltage supply device applies a bias voltage to a second component of each of the plurality of second image forming devices.

主权项

1. An image forming apparatus, comprising:
a first image forming device to form a first toner image, the first image forming device including a first photoconductive member and a first brush; a plurality of second image forming devices to form corresponding toner images; a first bias voltage supply device to apply a first bias voltage to a first component of the first image forming device; and a second bias voltage supply device to apply a second bias voltage to a second component of each of the plurality of second image forming devices, wherein each second image forming device includes a second photoconductive member that is rotatable and forms the corresponding toner image and a second brush to remove toner on a surface of each second photoconductive member; each second component is the second brush; each second image forming device includes a cleaning blade to remove remaining toner after the second brush removes the toner on the surface of the second photoconductive member; and wherein the second bias voltage supply device stops applying the second bias voltage to each second component at an earliest time among times at which each of the second photoconductive members stops rotating, when finishing each operation of image formation.
