摘要： The object of the present invention is to provide a resin particle having a protrusion that is more resistant to the detachment and having a uniform protrusion size and protrusion distribution density. The resin particle of the present invention comprises: a spherical part and a peripheral part having a plurality of convex part formed on the surface of the spherical part, wherein the spherical part and the peripheral part comprise a vinyl polymer and / or a polysiloxane component, the spherical part and the peripheral part are different in the composition, the melting point of the peripheral part is not less than 200 °C, and the curvature center of the boundary between the peripheral part and the spherical part determined by a transmission electron microscope observation of the cross-section of the resin particle exists in the spherical part.
