ABSTRACT:
To provide a pulverized toner excellent in the releasing ability and cleaning ability, and an image-forming apparatus for one-component developer, and a process cartridge using the pulverized toner. The pulverized toner contains a toner base particle containing at least a binder resin, a colorant, and a releasing agent, the mass ratio of the releasing agent to the binder resin is 3.0% to 6.0%, the adhesive force among the pulverized toners at 25° C. to 55° C. is 20 g to 80 g, and the pulverized toner is used for the image-forming apparatus for one-component developer containing the cleaning unit configured to dispose an elastic blade adjacent to the surface of the image bearing member so as to clean the surface.
