Amorphous polymer films are utilized in flexible photocopier belts primarily because they can be manufactured as large-area, thin-film photoreceptors that are physically flexible.1
In modern xerographic technology, these films are often employed in multilayer configurations where they serve distinct functional roles: one layer is designed to absorb light, while an adjacent layer facilitates the transport of electrical charge. By using amorphous materials, manufacturers avoid the functional complications associated with polycrystallinity and the high costs typically required to produce large single crystals, making them a practical and efficient choice for the continuous, large-area surfaces required in copier belts.12
