Abstract
A system for cooling a developer roll inside an image forming device. In one embodiment of the invention, the system for cooling the developer roll includes an air duct for carrying an airflow, the air duct having at least one opening to allow airflow to pass therethrough, and at least one toner cartridge in fluid communication with the air duct. The at least one toner cartridge includes the developer roll and at least one input port. The at least one input port is coupled to the at least one opening of the air duct to receive the airflow and to direct the received airflow towards end portions of the developer roll via a conduit and nozzles located within the toner cartridge. The system provides an effective way for introducing the airflow into the toner cartridge for cooling the developer roll.
