Toner used in electrophotography having toner particles and silica powder

Abstract

A toner is provided which can stably provide a favorable density stability, line reproducibility and dot reproducibility even in high-speed copying machines, printers and the like which form high resolution latent images over a long period regardless of environmental conditions, and can provide the image quality adaptable to embedded pattern printing, QR code printing and the like. The present invention is characterized in that the toner which includes toner particles including at least a binder resin and a colorant, and a fine silica powder, has a volume median diameter (D50) of not less than 0.70 μm and not more than 3.00 μm, and a total pore volume of not more than 0.200 cm3/g, measured in the range of the pore diameter from not less than 1.7 nm and not more than 300.0 nm.

Dependencies are inferred from the claim text.
