A transfer device which transfers a developer image formed on a surface of a photoreceptor drum to a transfer sheet is arranged so as to include a transfer drum for carrying the transfer sheet on a peripheral surface thereof, an electrode roller which can be moved to contact the transfer drum via the transfer sheet, and which can be moved apart from the transfer drum, and a control section for controlling contact start conditions between the transfer drum and the electrode roller. When the transfer sheet passes a spacing between the transfer drum and the electrode roller, the control section controls the contact start conditions in such a manner that a force is not exerted to a leading end portion of the transfer sheet from the electrode roller so as to separate the leading end portion from the transfer drum.
