ABSTRACT:
An embodiment may be an electrophotographic toner which comprises at least one toner particle which comprises an inner layer and an outer layer covering the inner layer, wherein a cross-sectional area ratio of the outer layer to the inner layer is 0.05-0.46, and wherein a non-uniform thickness exists in the outer layer, and further the average thickness (t) taken at 5 positions as calculated by, is about 0.2—about 1.0 μm, t=(t1+t2+t3+t4+t5)/5 (unit of t1-t5is μm)wherein t1represents a thickness of the thickest part of the outer layer, and t2-t5each represent a thickness of a second to a fifth thickest part of the outer layer in one particle, and wherein a glass transition point Tg of the inner layer is about 2—about 45° C. lower than Tg of the outer layer.
