<p>PROBLEM TO BE SOLVED: To provide an electrophotographic toner being excellently fixable at low temperature and having good anti-offsetting property and a wide fixation latitude and capable of oilless fixation. SOLUTION: The toner contains a bonding resin and a colorant and has 1 rad/sec angular frequency, >=1×105 Pa storage modulus at 30 deg.C (G'30), >=1×105 Pa loss modulus at 30 deg.C (G"30) and 45-110 deg.C melting point. When the common logarithm of G' is plotted to temperature and G' at (the melting point)+20 deg.C and G' at (the melting point)+50 deg.C are represented by G'(Tm+20) and G'(Tm+50), respectively, the condition of|logG'(Tm+20)-logG'(Tm+50)|<=1.5 is satisfied. When the common logarithm of G" is plotted to temperature and G" at (the melting point)+20 deg.C and G" at (the melting point)+50 deg.C are represented by G"(Tm+20) and G"(Tm+50), respectively, the condition of|logG"(Tm+20)-logG"(Tm+50)|<=1.5 is satisfied.</p> |
