Claims
- 1. A process unit mountable into and demountable from a main assembly, comprising:
- an image bearing member rotatable about a rotational axis thereof;
- process means actable on said image bearing member;
- a casing for supporting said process means and for rotatably supporting said image bearing member;
- a member for receiving a rotational drive force from the main assembly to rotate said image bearing member when said unit is mounted in the assembly;
- an electrically conductive member provided at the rotational axis of said image bearing member, for sliding contact with an electrically conductive member of said main assembly to electrically connect said conductive shaft with the conductive member of the main assembly.
- 2. A unit according to claim 1, wherein said image bearing member is a photosensitive member, and wherein said process means includes a charger.
- 3. A unit according to claim 1, wherein said drive force receiving means is integral with said image bearing member and is provided with a recess with which a rotatable projection of the main assembly is engageable.
- 4. A unit according to claim 1, wherein said unit is provided, adjacent the rotational axis, with a coupling portion for coupling with a member of said main assembly to correctly position said process unit, when it is mounted in the main assembly.
- 5. A unit according to claim 1, wherein said process unit is insertable into the main assembly in a direction in which the rotational axis of said image bearing member extends, and said electrically conductive shaft of said process unit is adjacent a leading end thereof in the direction of the insertion.
- 6. A unit according to claim 1, wherein said coupling portion is formed in said drive force receiving member.
- 7. A unit according to claim 1, wherein said drive force receiving means is engageable with a member in the main assembly for transmitting the rotational drive force to said process means.
- 8. A unit according to claim 1, wherein said conductive member is effective electrically to ground said image bearing member.
