摘要： An image forming apparatus, includes an image carrier; a power supply; a charging member, to which the power supply applies a direct current (DC) charging voltage, to charge a surface of the image carrier; and a controller. The controller causes the power supply to apply, to the charging member, the DC charging voltage of a sum of a reference voltage VC and a correction amount α, so that a charged potential VD of the surface of the image carrier assumes a target value that is substantially equal to the reference voltage VC; and to increase an absolute value of the correction amount α to be added to the reference voltage VC in inverse proportion to an absolute value of the reference voltage VC, when the absolute value of the reference voltage VC is smaller compared to a case in which the absolute value of the reference voltage VC is greater.

摘要： A disclosed image forming apparatus forms a toner image on a surface of a surface moving image bearing body and eventually transfers and fixes the toner image onto a recording medium to form an image on the recording medium and removes, by a cleaning apparatus, an adhered matter which is adhered to the surface of the image bearing body after the transferring. In the image forming apparatus, a glass transition temperature (Tg) of a toner is 40-60° C., and the cleaning apparatus causes a tip ridgeline portion of a blade member to be abutted against the surface of the image bearing body to remove the adhered matter from the surface of the image bearing body, and the tip ridgeline portion of the blade member is made of elastic rubber whose 100% modulus value at 23° C. is at least 6 MPa.
