Abstract
A toner having toner base particles each of which contains at least a binder resin and a colorant, and silica titania composite particles. The silica titania composite particles contain silica in an amount of from 55.0% by mass to 85.0% by mass; and, in a chart obtained by the measurement by X-ray diffraction of the silica titania composite particles and where, in respect of a peak having the highest diffraction intensity and a peak having the next-highest diffraction intensity among peaks present in the range of 2θ=24.0 to 29.0, the value of area of the peak on the lower-angle side is represented by Xa and the value of area of the peak on the higher-angle side is represented by Xb, the ratio of Xa/Xb is from 95/5 to 75/25.
