<p>PURPOSE:To provide the electrostatic charge image developing toner which substantially prevents the generation of stains of copies with lapse of time and has high quality by incorporating >=1 kinds of specific compds. into the toner. CONSTITUTION:This toner contains the compds. expressed by formula. In the formula, R<1> to R<3> respectively denote a (substd.) 1 to 24C alkyl group or (substd.) aralkyl; R<4> denotes a halogen atom or 1 to 8C alkyl group; A denotes a (substd.) arom. ring residue (including, for example, phenylene group, naphthylene group, anthlylene group). The percentage content of the compds. expressed by the formula in the toner is preferably 0.1 to 20 pts.wt. per 100 pts.wt. resin. The effect of improving electrostatic chargeability is not expected if the percentage content is too low. The quality of the toner degrades if the percentage content is excessively high and such contents are therefore undesirable.</p> |
