<p>PURPOSE:To provide a toner for developing an electrostatic charge image having sufficient extent of triboelectric charge and giving an image almost free from fog. CONSTITUTION:This toner for developing an electrostatic charge image contains a compd. represented by the formula as an electric charge controlling agent. In the formula, each of R<1>-R<4> is H, 1-18C hydrocarbon, alkoxy, aryl, aralkyl, hydroxyl, amino, nitro, carbonyl, sulfonyl or halogen, each of (j), (k), (m) and (n) is 0, 1, 2 or 3, j+k<=5, m+n<=5, R<1> and R<2> are different from each other, R<3> and R<4> are different from each other and plural RN's (N is 1, 2, 3 or 4) may be different from each other.</p> |
