<p>An image forming apparatus includes a main body, a sheet stack unit, an endless intermediate transfer member, a first transfer member for transferring a toner image onto the sheets conveyed from the sheet stack unit, at a nip formed between the intermediate transfer member and the first transfer member, and a second transfer member. In addition, a first voltage applying device applies a voltage to the first transfer member, a second voltage applying device applies a voltage having an opposite polarity to the second transfer member, and a controller controls the first and second voltage applying devices. In a timing when a leading edge of a first sheet reaches the nip, a trailing edge of the first sheet contacts a second sheet conveyed on the sheet stack unit, and wherein a period in which the controller causes the first voltage applying device and the second voltage applying device to apply the voltages to the first transfer member and the second transfer member, respectively, is at least from a time when secondary transfer onto the first sheet is started to a time when the trailing edge of the first sheet stops sliding on the second sheet stacked on the sheet stack portion.</p> |
