Toner

摘要

The present invention relates to a toner having a toner particle containing a binder resin containing a styrene acrylic resin and a block polymer, wherein the block polymer has a polyester segment and a vinyl polymer segment and has a melting point of 55° C. to 90° C., the polyester segment has a specific structure and a solubility parameter (SP) value of 9.40 to 9.85, and the vinyl polymer segment has a weight-average molecular weight (Mw) of 4000 to 15000.
