Abstract
A toner for developing electrostatic latent image is disclosed. The toner comprise of particles having a volume average particle diameter of from 3 to 8 μm, and said resin is obtained by either emulsion polymerization, mini-emulsion polymerization employing or suspension polymerization employing thioglycerin or at least one compound selected from compounds represented by the Formula (1) as the chain transfer agent. HS—R1—COOR2 (1) In the formula, R1 is an aliphatic group having carbon atoms from 1 to 10, which may have a substituent, and R2 is an aliphatic group having carbon atoms from 1 to 15, which may have a substituent.
