<p>A charging device includes a member to be charged; a charging member for charging the member to be charged, the charging member being contactable to the member to be charged and being supplied with a voltage; and wherein upon switching of the voltage from a DC component mode to a superimposing component mode of a DC component and an oscillation component, the DC component is decreased, and a peak-to-peak voltage of the oscillation component is increased in a period, and wherein the peak-to-peak voltage is changed from a first voltage which is smaller than twice a charge starting voltage of the member to be charged to a second voltage which is twice the charge starting voltage, while the peak-to-peak voltage is increasing. <IMAGE></p> |
