    摘要： An image forming apparatus includes a movable image bearing member; an image forming device for forming an image on the image bearing member; a charging member disposed opposed to the image bearing member; and bias application device for applying a bias voltage to the charging member, wherein the bias applying device effects a constant voltage control to the charging member when an image area of the image bearing member is in a charging region of the charging member, and effects a constant current control during at least a part of a period in which an area of the image bearing member other than the image area is in the charging region, and wherein a level of a constant voltage of the constant voltage control is determined during the constant current control.

    摘要： A charging device for contact-charging a member to be charged. A charging device for charging a movable member to be charged includes a contacting member adapted to contacting the member to be charged, and means for forming a vibratory electric field between the member to be charged and the contacting member, the vibratory electric field forming means applying between the members a vibratory voltage having a peak-to-peak value not less than twice an absolute value of a charge starting voltage to the member to be charged. The member to be charged can be uniformly charged.
