Toner for electrostatic charge development

Toner for electrostatic charge development

A toner comprising a binder resin, a coloring agent and a mold release agent, wherein the binder resin comprises a low-molecular-weight resin component, the low-molecular-weight resin component has a resin softening coefficient (A) represented by formula (1) of more than 0.165 and a storage modulus...

Zusammenfassung:A toner comprising a binder resin, a coloring agent and a mold release agent, wherein the binder resin comprises a low-molecular-weight resin component, the low-molecular-weight resin component has a resin softening coefficient (A) represented by formula (1) of more than 0.165 and a storage modulus (dyne/cm2) (G'(Tfb)) of 1104 or less when the outflow start temperature ( DEG C) as measured by an elevated flow tester is expressed as Tfb. A = |(lnG'(r1)-lnG'(r2))/(T1-T2)| formula (1) (In the formula, T1 represents the temperature ( DEG C) at which the storage modulus (G'(r1)) becomes 1105 (dyne/cm2) and T2 represents the temperature ( DEG C) at which the storage modulus (G'(r2)) becomes 1103 as measured using a viscoelasticity measurement apparatus under the conditions of a measurement frequency of 1 Hz and a measurement strain of 1 deg,and "| |" means an absolute value.)
