Abstract:
1. A process cartridge system, comprising: a drive transmission device that performs drive transmission; a primary rotating body configured to be driven by the drive transmission device; a secondary rotating body configured to be driven by the drive transmission device; a first involute spline joint configured to perform drive transmission to the primary rotating body to be driven; a second involute spline joint configured to perform drive transmission to the secondary rotating body to be driven, the first involute spline joint includes: the second involute spline joint includes: wherein the driven-side involute spline joint of the first involute spline joint is guided towards the driving-side involute spline joint of the first involute spline joint, and the driven-side involute spline joint of the second involute spline joint is guided towards the driving-side involute spline joint of the second involute spline joint, wherein a distance between the driven-side involute spline joint of the first involute spline joint and the driving-side involute spline joint of the first involute spline joint is less than a distance between the driven-side involute spline joint of the second involute spline joint and the driving-side involute spline joint of the second involute spline joint, in a state when the joints are not fitted.
