Electrostatographic toner composition.

摘要

An electrostatographic toner composition including a colorant and a resin, the resin being a polyether polymer containing repeating units of the following formula:
wherein R is a residue remaining subsequent to the removal of the hydroxyl groups from a dihydric phenol, R" is an aryl or alkyl radical, Z is the residue remaining subsequent to the removal of the hydroxyl groups from an alkylene ether glycol of the formula
wherein R' is a hydrogen atom, or methyl, n is an integer having a value of 2 to 4, and m is a number such that the polyether polymer has a reduced viscosity of from 0.2 to 0.6.
