ABSTRACT:
A method for developing electrical latent images is disclosed in which electrically formed latent images are developed by using a mixture of at least two different toners having the same polarity. The two or more different kinds of toners in the mixture have a difference in triboelectric charge between them less that 10 .mu.c/g. Furthermore, developing is carried out by using a liquid developer containing a mixture of at least two different toners having the same polarity. Each of the toners in the mixture should have a Zeta-potential more than 50 mV in absolute value and the difference in Zeta-potential between the different kinds of toners should be less than 50 mV.
