Generally, the lifespan of a photosensitive drum is very long, usually able to print up to 20,000 sheets. During use, only the consumed toner needs to be replaced. Application No. 202322947634.5 discloses a toner cartridge convenient for powder adding, including a toner cartridge. An adding port is opened on the outer surface of one end of the toner cartridge, and an opening and closing structure is arranged at one end of the adding port. The opening and closing structure is fixed on the outer surface of one end of the toner cartridge. The opening and closing structure includes an end face limiting rod, a first side rod, a second side rod, a sliding groove, a baffle, an anti-slip pattern, a rubber pad, a clamping member and a sliding block.
