Abstract
The present teachings describe a process for mixing comprising obtaining a dispersion of solid particles and an organic solvent wherein the dispersion comprises a particulate solid content of from about 0.5 weight percent to about 10 weight percent. The dispersion is mixed at a resonant frequency of the mixing system.

A process comprising:
- obtaining a dispersion of solid particles and an organic solvent wherein the dispersion comprises a particulate solid content of from about 0.5 weight percent to about 10 weight percent;
- and
- mixing the dispersion on a mixer that applies high intensity acoustic energy at a resonant frequency of a mixing system containing the dispersion.
A process of forming a charge generation layer comprising:
- mixing a dispersion of solid pigment particles, a binder and an organic solvent wherein the dispersion comprises a particulate solid content of from about 0.5 weight percent to about 10 weight percent;
- subjecting the dispersion to acoustic mixing at a resonant frequency of a mixing system containing the dispersion;
- coating the dispersion on a conductive substrate;
- and
- removing the solvent to form a charge generation layer.

A process of forming a charge transport layer comprising:
- mixing a dispersion of polytetrafluoroethylene, a binder and an organic solvent wherein the dispersion comprises a particulate solid content of from about 0.5 weight percent to about 10 weight percent;
- subjecting the dispersion to acoustic mixing at a resonant frequency of a mixing system containing the dispersion thereby producing a relative scattering index of less than about 0.1 in the dispersion;
- coating the dispersion on a conductive substrate;
- and
- removing the solvent to form a charge transport layer.
