PURPOSE: To ensure stable triboelectric chargeability and satisfactory mixability by incorporating resin particles, pigment particles and quat. ammonium hydrogensulfate as an electrostatic charge controlling agent. CONSTITUTION: Resin particles, pigment or dye particles and quat. ammonium hydrogensulfate as an electrostatic charge controlling agent are incorporated. The quat. ammonium hydrogensulfate is, e.g. trialkylammonium hydrogensulfate having alkyl groups such as distearylmethylammonium hydrogensulfate, trimethylammonium hydrogensulfate or triethylammonium hydrogensulfate. |
