An image bearing member unit (28) includes an image bearing member (3) on which a toner image is formed, and a support member (27) supporting the image bearing member such that the image bearing member protrudes through an opening (37) formed in the support member (27). The image bearing member unit is drawn out of and put into a main body (1) of an image forming apparatus. The image bearing member unit further includes a shutter (35) for covering and uncovering the image bearing member protruding through the opening (37) formed in the support member. The shutter (35) is assembled with the support member (27) to move in directions, substantially perpendicular to directions in which the image bearing member unit is drawn out of and put into the main body (1) of the image forming apparatus, to be located, when the image bearing member unit has been drawn out of the main body (1) of the image forming apparatus, in a closed position wherein the shutter (35) covers the image bearing member protruding through the opening (37) formed in the support member, and to be located, when the image bearing member unit has been set in a predetermined position inside of the main body of the image forming apparatus, in an opened position wherein the shutter (35) does not cover the image bearing member protruding through the opening (37) formed in the support member.
Description
[0001] The present invention claims Japanese Patent Applications No. 2002-276427, No. 2003-146785, and No. 2003-201356 and No. Priority 2003-201357, and related subject matter, is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to an image bearing member unit comprising an image bearing member on which a toner image is formed and a support member supporting the image bearing member, and which can be taken out and put in from an image forming apparatus, and to an image bearing unit comprising the A process cartridge for an image bearing member unit, and an image forming apparatus using the image bearing member unit or the process cartridge.
