Patent ID: 7033718

Claim:
A toner comprising: toner particles comprising: a binder resin; and a colorant, wherein the toner has such a rolling property as to relatively easily roll in one direction compared to other directions when the toner is present on a two-dimensional plane, wherein the toner satisfies the following relationships: 0.5≦( r 2 /r 1)≦0.8, 0.7≦( r 3 /r 2)≦1.0, and r 3≦ r 2 ≦r 1, wherein r1, r2 and r3 represent an average major axis particle diameter, an average minor axis particle diameter and an average thickness of the toner particles, and wherein the toner has a charge quantity of from 15 to 40 μC/g and a charge quantity distribution such that a half width of a charge quantity distribution curve is from 0.5 to 4.0 f C/μm.
