Title: Magnetic toner
Inventor: ISHIKAWA YOSHIBUMI
IPC: G03G9/083
Filed: 1995-04-28
Abstract: PURPOSE: To obtain a magnetic one-component toner excellent in environmental stability, especially stability to high temp. and humidity by regulating the Na content of a magnetic toner contg. a bonding resin and magnetic powder to a specified % or below. CONSTITUTION: The Na content of a magnetic toner contg. a bonding resin and magnetic powder is regulated to <=0.05%. In the case of a high Na content, image deterioration, especially insufficiency of density and unevenness of density are liable to occur because Na is liable to adsorb moisture contained in an atmosphere. Image deterioration is prevented by reducing the Na content to <=0.05%. Any thermoplastic resin generally used for a toner may be used as the bonding resin and polystyrene or polyacrylate resin is, e.g. used. Known magnetic powder of ferrite, magnetite, hematite, etc., may be used as the magnetic powder.
