ABSTRACT:
A capsule toner, comprising core particles of a core material exhibiting a cloud point within the range of from 30 to 90 and a penetration within the range of from 2 to 15, and a shell material coating the core particles. The capsule toner is preferably formed by dispersing the core particles in solution of the shell material in a good solvent for the shell material, and then adding a poor solvent for the shell material to cause the deposition of the shell material on the core particles.
