摘要： PROBLEM TO BE SOLVED: To provide a process device achieving stable transferring by rapidly raising or lowering ambient temperature of a transfer means by corresponding to a resistance value of the transfer means by simple control and an image forming apparatus provided with the process device. SOLUTION: With the generated voltage measured by a voltmeter 78 when measured current which is set beforehand is applied to a transfer roller 30 as index of resistance value for the transfer roll 30, a fan 66 is rotated in the suction direction when the generated voltage exceeds the high resistance threshold value and when the generated voltage is lower than the low resistance threshold value, the fan 66 is rotated at high speed in the discharging direction. Thus, stable transferring can be achieved by having the ambient temperature of the transfer roller 30 rapidly raised or lowered corresponding to the resistance value of the transfer roll 30 by the simple control.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of more excellently performing image formation on a 2nd side by referring to the transfer characteristic of a medium to be recorded itself. SOLUTION: By applying a constant current I1 to a transfer roller, a 1st side is printed (S3 and S5), and generated voltage V1 of the transfer roller is measured in the midst of printing (S7). Then, a transfer current to the 2nd side is set (S15 and S17) based on whether or not the voltage V1 is higher than a threshold (S13). Therefore, not only the electric characteristic such as the resistance value of the transfer roller but also the electric characteristic such as the resistance value of paper (medium to be recorded) are reflected on the voltage V1. By setting the transfer current to the 2nd side based on the voltage V1, the transfer current is controlled to an extremely desirable value fit to the paper, and the image formation (S21) on the 2nd side is extremely excellently performed.
