<p>PURPOSE:To provide a multi-color image forming system in which developing property, especially, noncontact developing property is stabilized and cleaning property is improved and whose device can be made small and simple. CONSTITUTION:An inorg. fluidizing agent having 50-120nm average particle size is added by m [vol%] to the toner particles having the average particle size D [mum]. The electrification potential difference (B-A) between toners with addition and without addition of the agent is specified to the relation of 3.0<=(B-A)/(m<2/3>)<=15.0, and 5.0/D<=x<=15.0/D. This toner is combined with a carrier and used for the image forming method of batch transfer system.</p> |
