Image forming device drum drive connection mechanism

Abstract

Abstract PURPOSE:To attain connecting with high precision and to prevent irregularities in the rotation of an image carrier by carrying out the connection of the image carrier to a driving source in such a manner that the image carrier and a driving/transmitting shaft are projected-recessed fitted and positioned, and by means of the magnetic force of both flanges when a process cartridge is attached to a device main body. CONSTITUTION:In the drum driving/connecting mechanism, one of the image carrier 1 and the driving/transmitting shaft 3 of a main body side is freely slid with respect to the other, and simultaneously, when one of them is slid, both of them are projected-recessed fitted, and positioned. Simultaneously, the flanges 4 and 8 provided on the image carrier 1 and the driving/transmitting shaft 3, respectively, are coupled by the magnetic force. Thus, when the process cartridge 9 is attached to the device main body, the connection of the image carrier to the driving source 3 can be carried out with high precision, the irregu larities in the rotation of the image carrier 1 is suppressed, and image quality can be improved.
