Abstract
An electrophotographic light receiving member comprising a substrate in a cylindrical form and a light receiving layer formed on said substrate, wherein said substrate has (i) a portion with an enlarged bore at least on the side of an end portion of said substrate and (ii) a portion in a tapered form situated next to and outside said portion (i). An electrophotographic apparatus provided with said electrophotographic light receiving member.
Claims82
An electrophotographic light receiving member comprising a substrate in a cylindrical form and a light receiving layer formed on said substrate, wherein said substrate has (i) a portion with an enlarged bore at least on the side of an end portion of said substrate and (ii) a portion in a tapered form situated next to and outside said portion (i).
An electrophotographic light receiving member comprising a substrate in a cylindrical form, a light receiving layer formed on said substrate, and a fixing member for sustaining said substrate which is equipped in mesh with said substrate on the side of at least an end portion of said substrate, wherein said substrate has (i) a portion whose bore is enlarged on the side of said end portion of said substrate and (ii) a tapered portion having a thickness which is gradually thinned than that of said portion (i) in a direction toward said end portion of said substrate, and said fixing member is provided in contact with said portion (i).
A substrate in a cylindrical form for an electrophotographic light receiving member, said substrate having (i) a portion with an enlarged bore at least on the side of an end portion of said substrate and (ii) a portion in a tapered form situated next to and outside said portion (i).
An electrophotographic apparatus comprising:
- a light receiving member comprising a substrate in a cylindrical form and a light receiving layer formed on said substrate, and a fixing member equipped in mesh with said drum-like shaped substrate on the side of at least an end portion of said drum-like shaped substrate for sustaining said drum-like shaped substrate, said light receiving member being made capable of being rotated by means of said fixing member,
- at least a charging means, a developing means and a transferring means which are provided about said light receiving member,
- a transporting mechanism for a transfer sheet onto which a developer is transferred, and
- an exposure means,
- wherein said substrate has (i) a portion whose bore is enlarged on the side of at least an end portion of said substrate and (ii) a tapered portion having a thickness which is gradually thinned than that of said portion (i) in a direction toward said end portion of said substrate, and said fixing member is provided in contact with said portion (i).
An electrophotographic apparatus including a light receiving member comprising a substrate in a cylindrical form and a light receiving layer formed on said substrate, wherein said substrate has (i) a portion whose bore is enlarged on the side of said end portion of said substrate and (ii) a tapered portion which is situated next to and outside said portion (i).
