Abstract
There is provided an electrostatic charge image developing toner comprising at least a binder resin, a coloring agent, and an aromatic hydrocarbon copolymer resin, wherein, in a toner particle, the percentage of dispersed aromatic hydrocarbon copolymer resin particles having a longitudinal diameter of 2.0 .mu.m or greater among the total number of dispersed aromatic hydrocarbon copolymer is 10% or less. The toner has superior effects of excellent grindability and not melting and adhering to apparatuses, without there being any adverse effect on basic abilities of the toner such as electrostatic charge property, fixing property, color, and the like.
