Embodiment Construction

[0064] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0065] figure 1 is a schematic diagram showing the overall configuration of an image forming apparatus to which the present invention is applied. figure 1 The illustrated image forming apparatus 1 is a so-called tandem type electrophotographic digital color printer. The image forming apparatus 1 is provided with an apparatus main body (apparatus main body) 1A, and an image forming processor 20 that performs image formation based on image data of each color is provided inside the apparatus main body 1A. Furthermore, the image forming apparatus 1 is provided with a controller 68 for controlling the operations of the respective units and devices provided inside the apparatus main body 1A. In addition, the image forming apparatus 1 is also provided with: an image processor 69 that performs predetermined image processing on image data recei...

Abstract

The present invention relates to an image forming apparatus, a method of allowing a driven member to be mounted on an apparatus body in an image forming apparatus and a method of allowing drive force to be transmitted to a belt unit in an image forming apparatus. The image forming apparatus includes: an apparatus body including a drive source; a driven member detachably attachable to the apparatus body; a first transmission member in the apparatus body, including a base rotatable around a rotation axis, and transmitting drive force from the drive source to the driven member; and a second transmission member in the driven member, including a base rotatable around the rotation axis, and transmitting drive force from the first transmission member to the driven member. Any of the first and second transmission members includes a projection, and the other includes a receiving port. The receiving port receives the projection when a rotation angle between the first and second transmission members is an angle set in advance while not receiving the projection when the rotation angle is out of the angle, at the time of mounting the driven member on the apparatus body.

Description

technical field [0001] The present invention relates to an image forming apparatus, a method of mounting a driven member to an apparatus main body in the image forming apparatus, and a method of transmitting a driving force to a belt unit in the image forming apparatus. Background technique [0002] If the photosensitive drum that is not used for image formation is rotated, the wear of the photosensitive drum by the cleaning blade, etc. is accelerated. Referring to Japanese Patent Application Laid-Open No. 7-181773, there is proposed a technique of switching photosensitive drums to be driven by changing the arrangement state of gears. [0003] A case is given where the driven member is provided so as to be detachably mounted on the main body of the image forming apparatus. In this case, if not only the driven member but also the device main body are allowed to have various states, the driven member and the device main body may be arranged in a relationship other than the pr...
