<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing erroneous paper feed. <P>SOLUTION: When an image formation is indicated (S11: YES), this image forming apparatus specifies a paper feed source (S12) and the specified paper feed source determines whether paper reverse is specified or not (S13). When determining that the paper reverse is specified (S13: YES), this apparatus applies an electric field of the same polarity with that of toner to a transfer roller (S14) and suppresses the transfer of a toner image. After increasing a fixing temperature, this apparatus controls the conveyance path (S 15 and S16), sets a route for reversing paper sheets and starts feeding the paper sheets (S17). <P>COPYRIGHT: (C)2008,JPO&INPIT |
