<p>PROBLEM TO BE SOLVED: To provide an electrophotographic toner and its manufacturing method good in potential acceptance and potential stability and good in transferability and transfer stability and good in storage stability. SOLUTION: This electrophotographic toner is manufactured by mixing a medium dispersing resin particles and a medium dispersing a colorant, coagulating the resin particles and the colorant, adding a medium dispersing fine inorganic particles to the medium containing the coagulated resin particles and the colorant at least once to attach the fine inorganic particles to the surfaces of the coagulated mixed particles, heating the obtained particles to coalesce them, and rinsing the obtained toner particles with an aqueous alkaline solution, preferably, an NaOH or KOH solution having a pH of 9.5-11.5, and then, water.</p> |
