Abstract

See full text

A toner comprising: a toner particle comprising a binder resin and a hydrocarbon wax; and inorganic fine particles, wherein the inorganic fine particles include silica fine particles surface-treated with specific polydimethylsiloxanes, a total amount of trimethylsilanol in the silica fine particles is from 1.0 ppm to 5.0 ppm, where a standard value of an amount of ions of an ester group is measured by time-of-flight secondary ion mass spectrometry, one or more peaks of the standard value are present within a range of 100 nm from the surface of the toner particle, and the maximum value A(d max) among the peaks of the standard value and the standard value A(0) on the surface of the toner particle satisfy the following relationships:

description='In-line Formulae' end='lead'1.05≤A(d max)/A(0)≤5.00,description='In-line Formulae' end='tail'

description='In-line Formulae' end='lead'A(0)≥0.010.description='In-line Formulae' end='tail'
