Protective shutter for image bearing member unit, and process cartridge and image bearing member unit, and process cartridge and image forming apparatus using the image bearing member unit
摘要：
An image bearing member unit includes an image bearing member on which a toner image is formed, and a support member supporting the image bearing member such that the image bearing member protrudes through an opening formed in the support member. The image bearing member unit is drawn out of and put into a main body of an image forming apparatus. The image bearing member unit further includes a shutter for covering and uncovering the image bearing member protruding through the opening formed in the support member. The shutter is assembled with the support member 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 of the image forming apparatus, to be located, when the image bearing member unit has been drawn out of the main body of the image forming apparatus, in a closed position wherein the shutter covers the image bearing member protruding through the opening 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 does not cover the image bearing member protruding through the opening formed in the support member.
摘要（中）：

图像承载部件单元（28）包括：图像承载部件（3），其上的调色剂图像被形成，并且支撑所述图象承载部件检查那样的支撑构件（27）在所述图像承载构件突出通过对开口（37）而形成 在支撑构件（27）。 图像承载部件单元被拉出并投入的图像形成装置的主体（1）。 图像承载部件单元还包括用于覆盖和不覆盖所述图像承载部件通过支撑部件形成的开口（37）突出的开闭器（35）。 快门（35）组装到支撑构件（27）的方向移动，基本上垂直于在所述图像承载部件单元被拉出的并投入所述主体（1）的图像形成装置的，以方向 被定位，当图像承载部件单元已伸出（1）图像形成装置，在worin快门闭合位置（35）覆盖所述图像承载部件通过所述开口突出（37）形成在所述主体的 的支撑构件和被定位，当图像承载部件单元已在图像形成装置的主体的内部的预定位置被设置，在worin快门（35）打开的位置不覆盖所述图像承载部件 通过开口突出（37）形成于所述支撑构件。
