Abstract
The invention disclosed concerns a method and an apparatus for transferring a toner powder image from a toner image bearing member to a transfer paper by pressure. In transferring the toner image, a pressure roller is placed in contact with the surface of the toner image bearing member under a pressure of at least 20 kg/cm.sup.2 and sliding is produced between the toner image bearing member and the transfer paper. Two different methods can be used to produce the sliding. The first method is to rotate the pressure roller at a speed different from the rotating speed of the toner image bearing member and the second method is to rotate the pressure roller so disposed to intersect its rotating axis with the rotating axis of the toner image member at an angle of about 0.5.degree. to 2.degree..
