Patent ID: 7906264

Claim:
An electrostatic latent image developing toner comprising: a non-crystalline resin, wherein the non-crystalline resin is a non-crystalline polyester resin having a component derived from an aromatic dicarboxylic acid, a crystalline resin having a melting point of 50 to 100° C., wherein the crystalline resin is a crystalline polyester resin having a sulfonyl group, and a colorant, and satisfying the relationship represented by the following formula (1), wherein A represents the content of the crystalline resin (% by mass) in the entire toner, and B represents the content of the crystalline resin (% by mass) in a classified toner which has been prepared by classifying the toner such that the volume average particle diameter thereof is in the range of (⅕)×D 50 T to (⅔)×D 50 T, wherein D 50 T represents the volume average particle diameter of the entire toner: 50≦( B/A )×100≦90 Formula (1).
