PURPOSE:To enhance durability by using specified polyester resin contg. an etherified diphenol component, dicarboxylic acid and polycarboxylic acid other than dicarboxylic acid as binding resin. CONSTITUTION:Polyester resin contg. at least 40-60mol.% etherified diphenol component basing on the total amt. of all the constituent monomers, 10-40mol.% dicarboxylic acid substd. by 6-16C hydrocarbon group or deriv. thereof and 1-20mol.% polycarboxylic acid other than dicarboxylic acid and/or polyol or deriv. thereof is used as binder resin. The polyester resin has 10<5>-2X10<6>P apparent melt viscosity at 100 deg.C, 2X10<4>-4X10<5>P at 110 deg.C and 55-70 deg.C peak heat absorption temp. in DSC and ensures satisfactory fixability, color mixability, triboelectric chargeability, high glossiness for enhancing the quality of an image and superior durability. |
