Abstract

PURPOSE:To obtain a toner which makes flocculating of toners to each other and sticking thereof to sleeves and carrier particles difficult by making one toner easier to flocculate to each other owing to pressure changes as compared to the other toner and increasing the average grain sizes thereof. CONSTITUTION:This developer consists of >=2 kinds of toner particle groups A and B. The toner of the group A is made larger in average grain size and is made easier to deform and to flocculate to each other when exerted with pressure as compared to the toner of the group B, whereby the toner which is fixed by low pressures is obtained. This toner has the advantage that the flocculating of the toner to each other and the sticking of the toner on sleeves and carrier particles are difficult. The toners A and B consist of binders (e.g.; hydrocarbon, fatty acids and their esters), coloring agents (e.g.; carbon black, etc.) and other additives.
