The conductive metal oxide which can be used in this case is fine powder which is transparent or white and has <=100OMEGA.cm volume resistivity value. Leak of charge arises hardly and the effect of the addition of the conductive metal oxide is not obtd. because of the high resistance if the volume resistivity value is larger than 100OMEGA.cm. The degradation in the image density is prevented while the increase of the charge of the toner and carrier is suppressed at the time of copying of many sheets. The copies which are free from a change in the image quality are thus obtd.
