摘要：
Disclosed is a toner for developing an electrostatic latent image, comprising colored particles containing a colorant and a binder resin, and hydrophobic particles, wherein said colored particles have a BET specific surface area of not less than 5 m.sup.2 /g and said hydrophobic particles satisfy the following relation:.vertline.pH.sub.A -pH.sub.B .vertline..ltoreq.1.0wherein said pH.sub.A is a pH value of said hydrophobic particles before heating and said pH.sub.B is a pH value of said hydrophobic particles after heating.
