An object of the present invention is to provide a toner which: is
excellent in fixing ability such as low-temperature fixability, hot
offset property, and separability even in a fixing system excellent in
quick start property and energy saving property; has high gloss; and is
excellent in development stability and transferability irrespective of
environments. The toner of the present invention includes toner particles
each containing at least a binder resin and a colorant, in which, in a
case where a tetrahydrofuran (THF) insoluble matter of the binder resin
in the toner when the toner is subjected to Soxhlet extraction with THF
for 2 hours is represented by A (mass %), a THF insoluble matter of the
binder resin in the toner when the toner is subjected to Soxhlet
extraction with THF for 4 hours is represented by B (mass %), a THF
insoluble matter of the binder resin in the toner when the toner is
subjected to Soxhlet extraction with THF for 8 hours is represented by C
(mass %), and a THF insoluble matter of the binder resin in the toner
when the toner is subjected to Soxhlet extraction with THF for 16 hours
is represented by D (mass %), A, B, C, and D satisfy the following
expression: (A-B)/2>(B-C)/4>(C-D)/8 where 40
