The invention discloses a processing cartridge, which comprises a powder tube, a sliding member and a mechanism for holding the sliding member, wherein the powder tube is used for receiving toner; the sliding member is capable of freely sliding in the powder tube; the mechanism for holding the sliding member is driven to close a powder outlet under the non-use state; a powder outlet portion is arranged on the powder tube; the powder outlet is arranged on the powder outlet portion; the sliding member closes the powder outlet under the action of the mechanism for holding the sliding member under the non-use state, and moves under the action of an external force to open the powder outlet under the use state; an internal member provided with an internal powder feeding opening is also arranged inside the powder outlet portion; the internal member and the powder outlet portion form certain space so that the sliding member is capable of sliding in the space formed by the powder outlet portion and the internal member; and the internal powder feeding opening of the internal member is butted with the powder outlet. Due to the adding of the internal member, resealing is achieved so that the toner cannot be leaked out. Therefore, the processing cartridge solves the technical problem that toner tends to be leaked out from a sliding member due to a gap between the sliding member and a powder outlet portion in the prior processing cartridge. |
