Abstract
An image forming apparatus includes development sections having development rollers, photosensitive drums, primary transfer rollers disposed opposite to the photosensitive drums in one-to-one correspondence, an intermediate transfer belt, and a voltage application section. The voltage application section includes a first voltage application section and a second voltage application section. In forced toner discharge from the development sections, the first voltage application section applies opposite polarity voltage between each of three upstream primary transfer rollers among the primary transfer rollers and the corresponding one of the photosensitive drums. The second voltage application section applies positive polarity voltage between a most downstream primary transfer roller and the corresponding one of the photosensitive drums.
