The invention relates to a carbon powder container regeneration method for a laser printer. The method comprises the following process steps: firstly, preparing a used carbon power container; secondly, demountably fixing a linker on the second cover when a second cover in a second pre-phase of a closed pulverized coal banker; thirdly, opposed connecting a powder storage bottle filled with carbon powder to a corresponding channel of the linker; then rolling the second cover through compressing a poking block by a starting poking block to ensures that the second pre-phase enters into a first pre-phase of an opened pulverized coal banker; finally, rolling the second cover to ensure that the first pre-phase enters into the second pre-phase so as to dismount the linker. The method used for recycling hollow carbon containers is characterized in convenient operation and high efficiency.
