Patent ID: 7115349

Claim:
A toner comprising toner particles containing at least a binder resin, a colorant and a release agent, and silica particles, wherein: the toner has a peak temperature of maximum endothermic peak in the range of 60 to 100° C. in a temperature ranging from 30 to 200° C. of an endothermic curve of differential scanning calorimetry (DSC) measurement; the silica particles contain a titanium element; and the silica particles satisfy the following expressions, 0.7≦( Ia 1 /Ib 1 )≦2.0; and 0.7≦( Ia 2 /Ib 2 )≦2.0 where Ia 1 represents a maximum intensity in the case of 2θ=25.3 deg, Ib 1 represents a mean intensity in the cases of 2θ=25.3 deg+2.0 deg. and of 2θ=25.3 deg.−2.0 deg., Ia 2 represents a maximum intensity in the case of 2θ=27.5 deg and Ib 2 represents a mean intensity in the cases of 2θ=27.5. deg+2.0 deg. and of 2θ=27.5 deg.−2.0 deg.
