Abstract

An image forming apparatus includes: an image holder that holds a toner image; a transferer that is disposed opposite to the image holder so as to be in contact with the image holder and transfers the toner image from the image holder onto a recording sheet that is going through a contact part where the transferer contacts the image holder, by applying a transfer voltage between the transferer and the image holder; a first power source that applies a voltage of a first polarity to the image holder; and a second power source that applies a voltage of a second polarity, which is reverse to the first polarity, to the transferer.
