Abstract
Disclosed is a useful method of removing a charge from an electrophotographic photoreceptor provided with insulation layers on its surface by radiating light containing a minimum of 6,000 angstroms of peak wave length onto said photoreceptor simultaneously with a corona discharge. To realize this, a filter is applied so that light containing a minimum of 6,000 angstroms of peak wave length can be generated.
