<P>PROBLEM TO BE SOLVED: To provide a driving force transmission mechanism, along with an image forming apparatus, capable of broadening an acceptable range of a deviation between a central axis of a driving force transmission member and a central axis of an input member. <P>SOLUTION: The driving force transmission mechanism 60 has a driving force transmission member 64 which can rotate integral with a rotation driving shaft 62B, can move forward and backward in an axial direction of the rotation driving shaft 62B, in which a tip end 64C can swing in a direction perpendicular to the axial direction and the tip end 64C is engaged with the inside of a recess 65A of an input member 65. In the rotation driving shaft 62B, in a state that a driving force receiving body (process cartridge 46) is mounted in a driving force supplying body, the tip end 64C of the driving force transmission member 64 overlaps with at least one part of the recess 65A as seen from the forward and backward direction, and a protrusion 64G which can be engaged to the edge of the recess 65A from an inner side is formed at a position deviated in a diameter direction from a rotation axis line L3, on a tip edge F1 of the driving force transmission member 64. <P>COPYRIGHT: (C)2011,JPO&INPIT |
