摘要

PROBLEM TO BE SOLVED: To provide a charging device capable of supplying the required amount of ions stably irrespective of the situation for making the occurrence of discharging difficult. SOLUTION: This charging device 3 before secondary transfer obtains the information about the state of the charging device 3 before secondary transfer by an image formation control part 42 or a temperature/humidity sensor 41. A voltage control part 33 sets or changes the conditions for applying voltage between a discharging electrode 22 and an induction electrode 23 based on the obtained information about the state of the charging device 3.
