Image forming device and control method thereof

A control method of an image forming device, the image forming device including an image bearing member, a charging member, a developing member, and a driving unit, the method comprising:

• adjusting a control timing for applying a voltage to the charging member and the developing member according to a current state of the image forming device, and controlling an operating state of the driving unit, to eliminate charges in an area on the image bearing member between a position corresponding to the charging member and a position corresponding to the developing member,
• wherein:
• the image bearing member is configured to rotate;
• the charging member is configured to charge a surface of the image bearing member by contacting the image bearing member;
• the developing member is located in a rotation direction of the image bearing member and in downstream of the charging member along the rotation direction, and the developing member is configured to supply developer to the image bearing member;
• and
• the driving unit is configured to drive the image bearing member, the charging member and the developing member to rotate, and
• wherein according to the current state of the image forming device, while the control unit adjusts the control timing to stop applying the voltage to the charging member, the image bearing member is driven by the driving unit to rotate only across the area on the image bearing member between the position corresponding to the charging member and the position corresponding to the developing member.
