发明名称 ELECTROPHOTOGRAPHIC TONER
摘要 <p>PROBLEM TO BE SOLVED: To provide a toner having such properties that the toner has a long life without decreasing characteristics of a conventional color toner and shows good transfer property even for a large-size objective body including a plain paper having a large value of surface roughness of paper, the image can be stored at higher temperature and can be fixed at lower temperature, and fixing can be performed even in an oil-less fixing device having no oil coating mechanism without causing offset or the like. SOLUTION: The electrophotographic toner contains toner particles containing internally added fine particles, and fine particles externally added. The internally added fine particles include fine particles (A) having <90 deg. contact angle with the binder resin. The externally added fine particles contain inorganic fine particles (B) having 0.005 to 0.2μm primary particle size and >90 deg. contact angle with the binder resin. The primary particle size (Ra) of the fine particles (A) and the primary particle size (Rb) of the inorganic fine particles (B) satisfy the relation of (Ra)<(Rb).</p>
