The resin has an average film thickness of 0.10 μm or larger and smaller than 0.45 μm. The coating layer has a porosity of 0.1% or higher and lower than 2.8%, when the porosity expressed by the following equation:


Porosity [%]=S1/S2×100

where, on a cross section of the coating layer, S1 represents a cross sectional area of the voids and S2 represents a cross sectional area of the resin.

摘要： A composite color toner image can be enhanced by applying a separate fluorescing toner image over it to provide an enhanced color toner image having a “pinkish” fluorescing effect. This separate fluorescing toner image is obtained using visible fluorescing dry magenta toner particles. Each of these toner particles consists essentially of a polymeric binder phase and a visible fluorescing colorant that emits at one or more peak wavelengths of at least 510 nm and up to and including 590 nm and that is dispersed within the polymeric binder phase.
