    Abstract: The invention provides a process for the manufacture of a toner which comprises the steps of: a) providing a latex dispersion containing primary resin particles and surfactant; b) providing a colorant dispersion containing primary colorant particles and surfactant; c) optionally providing a wax dispersion containing primary wax particles and surfactant; d) providing at least one carboxy functional compound of Formula (1), which may be in acid, salt and/or complex form: wherein R is a carbocyclic or heterocyclic radical which may be optionally substituted and Z1 is a bond or linker group, on condition that the amount of carboxy functional compound of Formula (1) provided in acid and/or salt form is at least 1.5% by weight, wherein the amount of carboxy functional compound is calculated according to the following equation: amount   of   carboxy   functional   compound   ( %   weight ) = 100 × weight   of   carboxy   functional   compound  ( weight   of   carboxy   functional   compound + weight   of   solids   content   of   latex , colorant   and   optional   wax   dispersions + weight   of   any   additional   surfactant ) e) mixing the latex dispersion, colorant dispersion, optional wax dispersion and said carboxy functional compound; and f) causing the particles in the mixture to associate. The process advantageously may produce a toner of small size and narrow particle size distribution. The present invention also provides a toner manufactured by the process.
