Appeal No. 1998-0126
Application 08/272,700
electrophotographic image forming apparatus comprising:
a discharge member having sharp dicharge ends,
wherein at least each discharge end portion including said
discharge end is coated with a material having a high electric
resistance.
5. A corona discharge device used in an
electrophotographic image forming apparatus comprising:
a discharge member having a plurality of sharp
discharge ends arranged in a row, wherein a distance D (mm) of
a space between a discharge end and a charge receiving member
to be charged in said image forming apparatus or between said
discharge end and a path of said charge receiving member, and
a pitch P (mm) between said discharge ends are determined to
establish a relationship of 4#D/P#6.
6. A corona discharge device used in an
electrophotographic image forming apparatus comprising:
a discharge member having sharp discharge ends,
wherein at least each discharge end portion including said
discharge end is made of an electrically conductive material
containing nickel in a range from 8% to 15% and chromium in a
range from 16% to 20%, and is coated with a material having a
high electric resistance.
