Amorphous silicon photoreceptors - have specific surface roughness achieved by polishing with reactive soft abrasive

摘要

Amorphous Si (hydride) photoreceptor has at least one of the following: mean surface roughness (needle type tester) of 190 Angstrom or less; mean surface roughness (electron microscope) of 60 Angstrom or less; a mean variance of roughnesses (electron microscope) of 70 Angstrom or less; max. surface amplitude (electron microscope) of 450 Angstrom or less; and difference between the mean of five largest and the mean of five smallest roughnesses (electron microscope) of 420 Angstrom or less. The surface is formed by reactive polishing and/or abrading.
