Electrophotographic recording material with uniform development - contains particulate inorganic photoconductors with different charging potentials

摘要

Recording material consists of an electrically conducting substrate and a light-sensitive layer contg. binder. This layer contains >=2 different types of particulate inorganic photoconductive which, when used alone, have different potentials when charged under the same conditions. The ratio between these is >1.5 and pref. 20. Typically ZnO is used. Better and more uniform development with a highly insulating magnetic toner is possible and, in partic. sufficient toner remains on the "sclid" areas. Pref. a highly insulating one-component developer is used.
