ABSTRACT:
An object of the present invention is to provide a toner having small-sized and potato-shaped particles created from multiple coherent spherical particles for excellent cleaning ability and high image quality, an image-forming method that realizes high image quality using the toner, and the like. To this end, there is provided a toner, which is produced by granulating toner materials as an organic phase comprising at least a binder resin and a colorant in an aqueous medium and has potato-shaped particles created from multiple coherent primary oil droplets of the organic phase in the aqueous medium.
