A pounce applicator comprises a roller assembly for coating an imprint. The roller assembly comprises a roller column and a pounce sleeve for discharging pounce. The roller column has a pounce storage chamber for storing pounce and a plurality of pounce outlets on the peripheral wall of the roller column which communicate with the pounce storage chamber. The pounce sleeve is sleeved outside the roller column, at least covering the plurality of pounce outlets of the roller column. The pounce sleeve is porous or semi-porous, and when an external force is applied on the pounce sleeve, the pounce sleeve exudes pounce out from the pounce storage chamber. The pounce of the present invention enables integrated storage. A tedious process of dipping powder slurry repeatedly by the user is avoided, and an operation mode is similar to that of the traditional brush.
