[0061]

As described above, according to the present invention,
Since the sticking portion on the outer surface of the process cartridge is partly separated from the back surface of the label, it is possible to easily peel off the stuck label when recycling the process cartridge. Further, this makes it possible to use a label coated with an adhesive or a double-sided tape over the entire surface, and it is not necessary to use a special label which is easy to peel off from the label itself, and there is an effect that the manufacturing cost of the label is low.

In the above, by making the sticking portion uneven, a part of the label can be stuck to the sticking seat surface. This concave and convex shape makes it possible to attach a part of the label to the attaching seat surface because the concave portion is separated from the label.

In the above, when the attaching portion is provided with the ribs surrounding the label, there is no fear that the label will be peeled off by handling the process cartridge. Further, by providing the ribs around the attaching portion, the label is less likely to be peeled off.
