Abstract
To provide a flange to be attached to an end of a photoconductor drum, the flange including: a drum engagement part capable of being engaged with an inner surface of the photoconductor drum; and a center hole, wherein the flange is prepared by cutting at least one of a surface of the engagement part and an inner surface of the center hole so that the axis of the center hole coincides with the axis of the photoconductor drum.
Claims13
A flange to be attached to an end of a photoconductor drum, the flange comprising:
- a drum engagement part configured to be engaged with an inner surface of the photoconductor drum;
- a center hole;
- and
- a flange part which is larger in outer diameter than the drum engagement part,
- wherein a groove is formed in the drum engagement part at a position near the flange part, and a diameter of the drum engagement part is 0.1 mm to 0.5 mm smaller at the groove than at an adjacent area of the drum engagement part in a direction away from the flange part, and
- wherein the flange is prepared by the process comprising:
- cutting a surface of the drum engagement part and an inner surface of the center hole so that an axis of the center hole coincides with an axis of the photoconductor drum.
A method for processing a flange which includes a drum engagement part configured to be engaged with an inner surface of a photoconductor drum and a center hole and which is to be attached to an end of the photoconductor drum, the method comprising:
- cutting a surface of the drum engagement part and an inner surface of the center hole so that an axis of the center hole coincides with an axis of the photoconductor drum in a state where the flange is engaged with the inner surface of the photoconductor drum;
- and
- providing a groove in the drum engagement part at a position near a flange part of the flange,
- wherein a diameter of the drum engagement part is 0.1 mm to 0.5 mm smaller at the groove than at an adjacent area of the drum engagement part in a direction away from the flange part.
A photoconductor drum, comprising:
- a drum;
- a flange attached to an end of the drum, the flange comprising a drum engagement part configured to be engaged with an inner surface of the drum, and a center hole;
- and
- a flange part which is larger in outer diameter than the drum engagement part,
- wherein a groove is formed in the drum engagement part at a position near the flange part, and a diameter of the drum engagement part is 0.1 mm to 0.5 mm smaller at the groove than at an adjacent area of the drum engagement part in a direction away from the flange part, and
- wherein the flange is prepared by the process comprising:
- cutting a surface of the drum engagement part and an inner surface of the center hole so that an axis of the center hole coincides with an axis of the photoconductor drum.
