<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus, a transfer current setting method and an image forming method optimally correcting transfer bias of a transfer means without deteriorating production capacity of a machine. <P>SOLUTION: By having the prescribed threshold value made to correspond to the detection result in the electric characteristic detection means varied according to the detection result by a temperature and humidity sensor, influence of temperature and humidity environment at the time can be eliminated in the image forming apparatus in correction of the current value carried out on the basis of a varied prescribed threshold value and the detection result of an electric characteristic detection means. Consequently, in the correction of the current value carried out on the basis of the detection result of the electric characteristic detection means and the varied prescribed threshold value at that time, only correction of the current value accompanied with resistance of a transfer means varied with time can be carried out without any influence from the temperature and humidity environment. In addition, by carrying out correction of the current value according to the temperature and humidity environment, setting of the current value made to flow into the transfer apparatus in total can be suitably carried out. <P>COPYRIGHT: (C)2008,JPO&INPIT |
