Abstract:
A charged positive toner having a positive polarity that attaches to a charge roller is moved from the charge roller to a photosensitive drum, and the positive toner is transferred to an intermediate transfer belt at a primary transfer portion at which a primary-transfer power supply forms an electric potential having a negative polarity. The primary-transfer power supply forms an electric potential having the positive polarity at the primary transfer portion, and the positive toner transferred to the intermediate transfer belt is moved together with the intermediate transfer belt and is collected by the charge roller in contact with a downstream photosensitive drum.

Claim (Index 1):
An image forming apparatus comprising:\n a first image-bearing member that bears a toner image; a movable belt that is in contact with the first image-bearing member and that forms a first transfer portion; a first charge member that is in contact with the first image-bearing member and that charges the first image-bearing member; a first developing unit that develops an electrostatic latent image formed on the first image-bearing member to form the toner image by using a toner and that can collect at least a charged toner having a first polarity that is a regular charge polarity of the toner among residual toners on the first image-bearing member after the toner passes through the first transfer portion as a result of rotation of the first image-bearing member; a second image-bearing member that is disposed downstream of the first image-bearing member in a direction in which the belt moves, and in contact with the movable belt to form a second transfer portion; a second charge member that is in contact with the second image-bearing member and that charges the second image-bearing member; a second developing unit that develops an electrostatic latent image formed on the second image-bearing member to form a toner image by using a toner and that can collect at least a charged toner having the first polarity among residual toners on the second image-bearing member after the toner passes through the second transfer portion as a result of rotation of the second image-bearing member; a common potential formation unit that forms electric potentials having the same polarity at the first transfer portion and the second transfer portion; and a control unit that controls the first charge member, the second charge member, and the potential formation unit, wherein the control unit controls the first charge member such that a charged first toner that has a second polarity opposite to the first polarity and that attaches to the first charge member is moved to the first image-bearing member, and controls the potential formation unit such that the first toner is transferred from the first image-bearing member to the belt at the first transfer portion and the first toner transferred to the belt is moved to the second image-bearing member at the second transfer portion, and controls the second charge member such that the second charge member collects the first toner moved to the second image-bearing member.
