Claim 0:
1. A toner comprising:
a toner particle containing a resin component and a wax; and
an inorganic fine particle on a surface of the toner particle, wherein in the cross section of the toner particle, domains including the wax are present in a first region ranging from a surface of the toner particle to a depth of 600 nm from the surface, wherein
when a percentage ratio of sum of areas of all the domains present in the first region with respect to an area of the first region is defined as R2, and
when a percentage ratio of sum of areas of the domains having a major diameter of 10 to 120 nm present in the first region with respect to the area of the first region is defined as R1, R1 and R2 satisfy the following formulae (1) and (2):

2.0≤R1(%)≤15.0  formula (1)

R1(%)/R2(%)≥0.60  formula (2).
