Abstract
An electrostatic-image developing toner includes toner particles, inorganic particles externally added to the toner particles, and a low-molecular-weight siloxane having a molecular weight of 200 or more and 600 or less. The low-molecular-weight siloxane includes only a siloxane bond and an alkyl group. The total content of the low-molecular-weight siloxane in the electrostatic-image developing toner is, by mass, 0.01 ppm or more and 5 ppm or less.
