Original Abstract Submitted
An image forming apparatus comprises a transferer transferring a toner image on an image carrier onto a sheet, and facing the image carrier; a fixer fixing the toner image on the sheet; and a controller applying transfer voltage for transferring the toner image onto the sheet, wherein the transferer defines a transfer nip for passing the sheet between the image carrier and the transferer, the fixer includes a heating portion and a pressing portion, and passes the sheet after passing through the transfer nip through a fixing nip between the heating portion and the pressing portion, and the controller controls the transfer voltage in such a way that transfer current flowing through the transfer nip is made constant at a setting value, and increases the setting value of transfer current after a leading end of the sheet passes through the transfer nip and before it passes through the fixing nip.
