PROBLEM TO BE SOLVED: To provide a transfer device in which a neutralizing mechanism provided in the vicinity of the transfer device is improved, and deterioration in image quality of a transfer image by charging is prevented without a leakage of a transfer bias, and to provide an image forming apparatus having the transfer device. SOLUTION: In the image forming apparatus having the indirect transfer device, the neutralizing mechanism (x1) is provided on at least one of conveying path proximal members installed on conveying paths A, B in a vicinity of a secondary transfer position, and is grounded by using a conducting material via a neutralizing circuit (13) that includes a resistor (12) with a prescribed resistance value and a ground switch (11) electrically connected in parallel to each other. The ground switch is turned off at least at a time of applying the secondary transfer bias to prevent a leakage of the secondary transfer bias, and turned on for a prescribed time at a time other than the time of applying the secondary transfer bias to ground and remove an accumulated static electricity from the conveying path proximal member.
