Photosensitive drum for printer cartridge and method for mounting the same
A photosensitive drum for a printer cartridge, which can be easily mounted on a printer cartridge of which the positions of drum connectors are fixed, is disclosed. The photosensitive drum for a printer cartridge comprises a cylindrical drum having a photosensitive layer on a cylindrical surface thereof; and a pair of rotation shafts which is respectively mounted on the sides of the cylindrical drum for rotating and supporting the cylindrical drum, wherein at least one of the rotation shafts is insert-fitted to the side of the cylindrical drum.
1. A method for mounting a cylindrical photosensitive drum on a printer cartridge, comprising the steps of:
inserting a first rotation shaft into a first drum connector of a pair of drum connectors, which are fixed on a cartridge frame and separated by a predetermined distance, wherein the first rotation shaft has a shape of being insert-fitted to a first side of the cylindrical photosensitive drum;
inserting a second rotation shaft connected with a second side of the cylindrical photosensitive drum into a second drum connector of the pair of drum connectors; and
insert-fitting the first rotation shaft to a first side of the cylindrical photosensitive drum by pushing the first rotation shaft to the direction of the cylindrical photosensitive drum.
2. The method for mounting a cylindrical photosensitive drum on a printer cartridge of claim 1 , wherein the first rotation shaft includes:
a shaft body which is inserted into the first drum connector, and rotates and supports the cylindrical drum; and
a shaft connector which is insert-fitted to the first side of the cylindrical drum, and accordingly connects the first drum connector and the cylindrical drum.
