Claim:
1. A toner, comprising a toner particle comprising a core particle containing a binder resin and a colorant; the toner particle having a protrusion on a surface thereof, the protrusion containing an olefin-based polymer having a cyclic olefin structure containing a copolymer obtained from an acyclic C an average radius of curvature of the protrusion Rs (μm) is 0.004Rc to 0.100Rc μm and an average of a surface coverage 100×S1/S is 5 to 90%, when an average particle diameter of the core particle is defined as Rc (μm), a projected area of the toner particle is defined as S, and a projected area of the protrusion is defined as S1, Rs (μm), Rc (μm), S and S1 being calculated from a planar projected image of an image of the toner particle photographed with a scanning electron microscope.
