Abstract:
    Disclosed is a method to get high quality image by improving the transfer capability of the developing agent. The solution is applied by using a first developing agent containing a first additive having a small average particle diameter, followed by using a second developing agent containing a second additive having a large average particle diameter larger. Alternatively, a first developing agent containing a first toner having a small roundness is used first, followed by using a second developing agent containing a second toner having a large roundness. Still alternatively, a first developing agent containing a small amount of a first additive is used first, followed by using a second developing agent containing a large amount of a second additive.
