IMAGE FORMING APPARATUS, IMAGE FORMING METHOD AND IMAGE FORMING PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect an exacter AC electrifying current flowing to a photoreceptor and further to output the appropriate AC electrifying current corresponding to the change of printing speed.

SOLUTION: The AC electrifying current Ia flowing to an apparatus GND via an AC electrifying current detection circuit 4.1 from a photoreceptor GND is detected as the exacter AC electrifying current which is not influenced by the stray capacitance of an electrification path.
