A toner including toner particles including a binder resin, a colorant,
and an inorganic particulate material present on a surface of the toner
particles. The toner particles have a surface roughness (Ra) of from 1 to
30 nm, a standard deviation of the surface roughness of from 10 to 90 nm
and include 1 to 20 convexities per 1 .mu.m, which have a height not less
than 10 nm.
