PURPOSE:To improve low-temp. fixability and blocking resistance by incorporating a specific vinyl polymer, aliphat. alcohol and polyolefin wax as essential components into the above toner. CONSTITUTION:This toner is formed by incorporating 100pts.wt. vinyl polymer having 2 to 400,000wt. average mol. wt. and >=60 deg.C glass transition point, 1 to 40pts.wt. aliphat. alcohol essentially contg. at least 90wt.% 15 to 90C aliphat. alcohol having <=90 deg.C m. p. and 1 to 20pts.wt. polyolefin wax having <=10 penetration number at 25 deg.C into the toner. The low-temp. fixability, offset resistance and blocking resistance are improved in this way and further the staining of a photosensitive drum is prevented. |
