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.
