The image forming apparatus of the present invention includes a first and a second main conveyance path, a first and a second processing unit, a transfer unit, and a fixing unit. The first and second main conveyance paths come together after having branched apart between a paper supply unit and a paper delivery unit. A recording medium is selectively conveyed along either one of the first and second main conveyance path. Image formation is performed by a method of electrophotography by, alternatively, either the first or second processing unit. Between the first and second main conveyance paths where they are branched apart, the transfer unit generates a transfer electric field between itself and one or the other of the first and second processing unit. The fixing unit controls the temperature of a first or a second fixing roller, which are disposed in the first and second main conveyance path after they have come together, alternatively.
