Abstract
PURPOSE: To achieve excellent and stable pressure fixation to ordinary paper and enable multiple copying, by specifying the rate of thickness of insulating outer shell with respect to the core material of toner and the grain size distribution of toner.
CONSTITUTION: The main grain size of capsule toner (the grain diameter occupied by the maximum number of particles in the grain size distribution) a is within the range of 5 to 25μ, and the main grain size of the core material containing toner of main grain size ±3μ or less by more than 70% (in quantity), preferably more than 80% (in quantity), is supposed to be b. In this condition, it is adjusted to satisfy the relation of formulaI, or preferably formula II. If (a-b)/b is less than 0.02, the toner charging characteristic and durability may be inferior, or if more than 0.04, toner making may be difficult and other problems may be caused.
