According to the novel processing box 100 provided by the invention, on one hand, the end part of the photosensitive element 11 in the waste powder bin unit is only connected with the driving force receiving part 13 to receive the rotating driving force of the printer driving part, the driving force receiving part 13 firstly drives the photosensitive element 11 to rotate, and the developing element 15 is engaged by the rotating photosensitive element 11 to rotate, namely, the processing box 100 is in a printing working state; on the other hand, the pushing force of the printer pushing part is received by toggling the lever member 17, the driving force receiving part 13 is driven to contract and move from the combining position to the disengaging position relative to the driving force engaging part 111 along the axial direction, at the disengaging position, the driving force receiving part 13 disengages from the printer driving part, that is, the processing box 100 does not form images, at this time, the photosensitive element 11 and the developing element 15 stop rotating, at this time, the photosensitive element 11 and the developing element 15 are kept at the original position without separation, and the waste powder bin unit and the powder bin unit do not need to be arranged in a relative rotation mode.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
