Claim:
1. A transfer device comprising: a transfer body that receives a transfer bias and transfers a toner image held on an image carrier which is rotating onto a sheet sandwiched between the transfer body and the image carrier, the toner image being generated by developing an electrostatic latent image formed on the image carrier by using toner; a resistance value measuring unit that measures a resistance value which is determined by a voltage and a current of the transfer bias; and a contact pressure adjusting unit that adjusts a contact pressure of the transfer body against the image carrier so that the transfer body will contact the image carrier at a second contact pressure which is determined based on a first contact pressure, the second contact pressure being equal to or higher than the first contact pressure, the first contact pressure being located at a position at which the resistance value measured by the resistance value measuring unit reaches a predetermined threshold.
