ABSTRACT:
In a method of adjusting image forming conditions according to the present invention, it is judged whether or not a humidity detected by a humidity sensor is not less than a predetermined first humidity H.sub.1 (step W6). As a result, when it is judged that the humidity is not less than the first humidity H.sub.1, a main charger table is accessed using the detected absolute humidity as an address, and corresponding additional data G is read out (step W7). The additional data G read out, together with additional data E and main charger driving time adjustment data F, is added to main charger reference data K.sub.2, so that main charger voltage data C.sub.2 is produced (step W8). On the other hand, when the detected humidity is less than the first humidity H.sub.1, a voltage to be applied to a main charger is not adjusted depending on the humidity.
