Abstract

The present invention provides a toner which can form a stable image even in a low print intermittent mode under a low-temperature and low-humidity environment, while having excellent charge rising property. A toner includes a toner particle and a silica fine particle A, wherein (I) in TOF-SIMS measurement of the toner particle, a fragment peak derived from a boron atom and a fragment peak derived from a BO structure are detected, and the toner contains dodecylbenzenesulfonic acid or a dodecylbenzenesulfonate; (II) in TOF-SIMS measurement of the silica fine particle A, a fragment ion is observed which corresponds to a dimethylsiloxane structure; when 2.00 g of the silica fine particle is dispersed in a mixed liquid of 25.0 g of ethanol and 75.0 g of an aqueous solution of 20% by mass of NaCl, and the dispersion is subjected to a titration operation which uses sodium hydroxide, Sn defined by Sn=[(a−b)×c×NA]/(d×e) satisfies 0.10≤Sn≤0.80.
