ELECTROSTATIC LATENT IMAGE DEVELOPING TONER

摘要

PROBLEM TO BE SOLVED: To provide an encapsulated toner which is excellent in low temperature fixability, anti-offset properties and blocking resistance, suppresses filming on a developing roller and a photoreceptor, and can stably form clear images many times. SOLUTION: In the encapsulated electrostatic latent image developing toner consisting essentially of a colorant and a binder resin, a capsule wall contains a powdery material whose heat conductivity at 300 K is Y (W/mK) in an amount of M (vol.%) based on the amount of the capsule wall, and when the thickness of the capsule wall is represented by r (nm), the toner satisfies the expression (1): (r/100)2
