A transfer device comprising: a transfer section which forms a nip portion between the transfer section and an image carrier and transfers a toner image on an image carrier onto a sheet passing through the nip portion; an application section which applies a voltage to the transfer section; a determining section which determines a timing of applying voltage from the application section to the transfer section, wherein the control section controls the application section to apply a voltage having an opposite polarity to a transfer polarity to the transfer section until the timing determined by the determination section in a period since a leading edge of the sheet in a conveyance direction advances into the nip portion until a predetermined non image area of the sheet has passed through the nip portion, and then, at a timing determined, switch to apply a voltage having the transfer polarity.
