Abstract
A developing portion forms a toner image, which corresponds to a recording image, with a toner which has been electrically charged to a predetermined electrical potential. A transfer portion, to which an electric potential, different from the electric potential of the toner image, is applied, transfers the toner image onto a recording medium. A first transfer-electric-potential applying portion applies a transfer electric potential to the transfer portion. A carrying portion carries the recording medium so as to cause the recording medium to pass by the transfer portion. A second transfer-electric-potential applying portion sets the recording medium and the carrying portion to cause the recording medium and the carrying portion to have a predetermined electric potential corresponding to the transfer electric potential of the transfer portion.
