<p>PURPOSE:To provide a method for always forming an image which is excellent in image quality as to a cleanerless image forming method in which developing and cleaning are performed at the same time at a developing stage. CONSTITUTION:As to the cleanerless image forming method, developing toner used is of the following kind respectively selected and set like, (a) intrinsic electric resistance value R satisfies R>=1X10<13>OMEGA.cm and the electrostatic charged amount qt of the developing toner is 0.5[mC/kg]<=¦qt¦<=40[mC/kg], or (b) the charge amount qr which residual toner remaining on the surface of a photosensitive body after transfer has after passing a latent image forming stage is 0.5[mC /kg]<=¦qr¦<=60[mC/kg], or (c) the amount km0 of the developing toner facing a latent image at a developing stage is 0.6[X10<-2>kg/m<2>]<=km0<=3.0[X10<-2>kg/m<2>]. In this method, the high-quality image without a positive memory and a negative memory is always and easily obtained.</p> |
