Abstract:
1. An electrostatic latent image developing toner comprising: toner particles each of which has a shell layer on the surface of a core particle comprising at least a first binder resin having a softening point of less than 100° C., a second binder resin having a softening point of not less than 100° C., was and a colorant, wherein the core particle is formed by allowing at least first binder resin particles, second binder resin particles and colorant particles to aggregate/fusion-adhere to one another, and a process in which the shell layer is formed by allowing shell-layer-forming binder resin particles to adhere/fuse onto the surface of the core particle is carried out; wherein the shell layer has a multiple layer structure with two or more layers and the constituent resin of the outermost layer has a glass transition point of 55-75° C.
