<p>PROBLEM TO BE SOLVED: To obtain a one-component developer that retains good developing performance over a long period of time, suppresses the occurrence of fog, etc., and has good cleanability. SOLUTION: The one-component developer consists of toner particles containing at least a bonding resin and a colorant and an additive consisting of a small particle diameter additive and a large particle diameter additive added in such a way that the amount SA of the small particle diameter additive stuck weakly is adjusted to <=20 wt.%, the amount SB of the small particle diameter additive stuck strongly to <=10 wt.%, the amount LA of the large particle diameter additive stuck weakly to <=55 wt.% and the amount LB of the large particle diameter additive stuck strongly to <=5 wt.%, based on the total amount of the additives.</p> |
