Abstract

The image forming apparatus is provided with: plural rotating members that are arranged rotatably; plural rotation side coupling members that are provided corresponding to the respective rotating members and transmit drive force to the respective rotating members; plural drive side coupling members that are connected to the respective rotation side coupling members and rotate and drive the respective rotating members via the rotation side coupling members; and an interconnecting unit that connects a predetermined number of the drive side coupling members among the plural drive side coupling members to the corresponding rotation side coupling members.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a printer and a copier, and a drive switching method. Background technique [0002] In an image forming apparatus of a so-called tandem system having photosensitive drums of respective colors, it is not always necessary to form a full-color image, but it is necessary to form a monochrome (for example, black) image in some cases. In this case, if the photosensitive drum not used in the image formation process is rotated, the cleaning blade or the like tends to cause abrasion or the like to the photosensitive drum. [0003] Therefore, a technique of switching the photosensitive drum to be driven by changing the arrangement condition of the gears has been proposed (for example, refer to Patent Document 1: Japanese Patent Application Laid-Open No. 7-181773). [0004] It is an object of the invention to improve the driving accuracy of rotating parts or the like arranged to be switchably dr...
