Abstract
A photoluminescent toner includes a photoluminescent toner particle that contains a binder resin, a release agent, and a photoluminescent pigment and has a release agent domain, and a silicone oil-treated silica particle that is externally added to the photoluminescent toner particle, in which in observation of a cross section of the photoluminescent toner particle, an average major axis length Dw of the release agent domain and an average major axis length Dp of the photoluminescent pigment satisfy Expression (1). 0.3≤Dw/Dp≤1.0 Expression (1):
