Abstract
A toner cartridge includes a housing having a space for toner, and a cover forming a toner storing space within the housing. The cover is secured to the housing with an expandable hot-melt elastic adhesive to prevent toner leakage. This arrangement improves assembly of the cartridge, and allows the discarded cartridges to be recycled.
