Method for fixing bearing member for cylindrical substrate, structure for fixing bearing member for cylindrical substrate, electrophotographic photoreceptor having bearing member, print cartridge, and apparatus for forming image

A structure for fixing a bearing member to a cylindrical substrate comprising:

• a cylindrical substrate;
• a bearing member interdigitated on an outer periphery of the cylindrical substrate;
• a first inserting member having an axial opening and prongs expandable radially;
• and
• a second inserting member internally insertable into the axial opening of the first inserting member,
• wherein, upon insertion of the second inserting member into the axial opening of the first inserting member, the second inserting member engages and radially expands the prongs of the first inserting member along with the cylindrical substrate to clamp the bearing member to the cylindrical substrate.

An electrophotographic photoreceptor having a fixed bearing member, comprising:

• an electrophotographic photoreceptor;
• a bearing member interdigitated on an outer periphery of the electrophotographic photoreceptor;
• a first inserting member insertable into an axial end of the electrophotographic photoreceptor, the first inserting member having an axial opening and prongs expandable radially;
• and
• a second inserting member internally insertable into the axial opening of the first inserting member,
• wherein, upon insertion of the first inserting member into the electrophotographic photoreceptor and insertion of the second inserting member into the axial opening of the first inserting member, the second inserting member engages and radially expands the prongs of the first inserting member along with the cylindrical substrate to clamp the bearing member to the cylindrical substrate.
