Abstract
An electrostatic latent image developing toner comprising at least a resin, a wax and a colorant, wherein the wax comprises 40 to 98% by mass of a first release agent comprising an ester wax and 2 to 60% by mass of a second release agent comprising a hydrocarbon having at least one of a branched chain structure and a cyclic structure; and the colorant comprises a silicon phthalocyanine represented by Formula (I):
Claims12
An electrostatic latent image developing toner comprising at least a resin, a wax and a colorant, wherein
- the wax comprises 40 to 98% by mass of a first release agent comprising an ester wax and 2 to 60% by mass of a second release agent comprising a hydrocarbon having at least one of a branched chain structure and a cyclic structure;
- and
- the colorant comprises a silicon phthalocyanine represented by Formula (I):
- wherein Z1 and Z2 each independently represent a hydroxyl group, a chlorine atom, an aryloxy group of 6 to 18 carbon atoms, an alkoxyl group of 1 to 22 carbon atoms or a group represented by Formula (IV);
- Ra1, Ra2, Ra3 and Ra4 each independently represent a substituent;
- and na1, na2, na3 and na4 each independently represent an integer of 0 to 4,
- wherein R1, R2 and R3 each represent an alkyl group of 1 to 22 carbon atoms, an aryl group of 6 to 18 carbon atoms, an alkoxyl group of 1 to 22 carbon atoms or an aryloxy group of 6 to 13 carbon atoms, wherein R1, R2 and R3 each may be the same or different.
