Abstract:
The invention provides: an electrostatic latent image developing toner comprising a non-crystalline resin, a crystalline resin having a melting point of 50 to 100° C., 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)×D50T to (⅔)×D50T, wherein D50T represents the volume average particle diameter of the entire toner, and a method for producing the same, as well as an electrostatic latent image developing developer, a toner cartridge, a process cartridge, and an image forming apparatus using the same. 50≦(B/A)×100≦90 Formula (1)
