Abstract
Provided is a toner, including: a toner particle; and an organic-inorganic composite fine particle on a surface of the toner particle, in which the organic-inorganic composite fine particle includes: a resin fine particle; and an inorganic fine particle embedded in the resin fine particle, and part of which is exposed to a surface of the composite fine particle, and in which the composite fine particle satisfies the following relationships: (i) in viscoelasticity measurement of the composite fine particle, when the loss elastic modulus thereof at a temperature T (° C.) is represented by G″[dN/m], a change ratio d(Log(G″))/dT of a common logarithm of the loss elastic modulus has a minimum in a temperature range of from 60° C. to 150° C., and the minimum is less than −0.10; and (ii) the loss elastic modulus (G″) thereof at a temperature of 180° C. is 1.0×10dN/mor more and 1.0×10dN/mor less.
