We claim the ornamental design for an image drum cartridge, as shown and described.
FIG. 1 is a front elevation view of an image drum cartridge, showing our new design;
FIG. 2 is a rear elevation view thereof;
FIG. 3 is a right-side elevation view thereof;
FIG. 4 is a left-side elevation view thereof;
FIG. 5 is a top plan view thereof;
FIG. 6 is a bottom plan view thereof;
FIG. 7 is a top perspective view thereof; and,

The broken line showing of the image drum cartridge is for the purpose of illustrating portions of the “article” and forms no part of the claimed design.
The wire frame lines shown throughout the views at the edges are intended to indicate surface contour.
