Toner

摘要

Toner used for electrophotographic development includes additives such as inorganic fine particles, having a particular particle diameter and specific surface area, and hydrophobic silica having a particular specific surface area and surface treatment, so that the toner can provide images of high quality without generating photoconductor filming. The toner is applied to the electrophotographic method including the developing step of forming electrostatic latent images on a photoconductor containing a stationary magnet, magnetically attracting the toner to the surface of the photoconductor in a toner sump, and collecting toner at a non-image section by an electrode roller; the transferring step of transferring the toner to transfer paper; the cleaning step of removing residual toner left on the photoconductor in the transferring step; and the recycling step of recycling the residual toner. Toner used for an electrophotographic method using an intermediate transfer member includes additives such as inorganic fine particles, having a particular particle diameter and specific surface area, arid hydrophobic silica having a particular specific surface area and surface treatment, so that the toner can provide images of high quality and high transfer efficiency without generating photoconductor and intermediate transfer member filming.
