<p><P>PROBLEM TO BE SOLVED: To provide a yellow toner which has excellent blocking resistance, preservability under a high-temperature environment, low-temperature fixability, high-temperature offset resistance, glossiness, OHP transparency, and transferability and can form high-definition and high grade images. <P>SOLUTION: The yellow toner contain at least a binder resin, a wax and a coloring agent and is characterized in that the modulus of elasticity in storage (G'<SB>80</SB>) at 80°C of the toner exists in the range from 1×10<SP>6</SP>to 1×10<SP>8</SP>[dN/m<SP>2</SP>]; the loss section (tanδ) at 140°C exists in the range from 0.2 to 1.5 and the toner contains a compound expressed by the following general formula (1) as the coloring agent at 2 to 15 parts by mass per 100 parts by mass the binder resin and the wax at 0.5 to 10 parts by mass per 100 parts by mass the binder resin. <P>COPYRIGHT: (C)2003,JPO</p> |
