The utility model relates to a roller type ink pad, aiming to solve the problems of uneven seal staining caused by asynchronous seal slide and staining rubber roll rotation due to the condition that a seal consumes more labor for driving a staining rubber roll to rotate and uneven seal staining caused by an indirect staining way existing in the traditional rotating type oiling ink pad. The drum type ink pad is characterized by comprising an ink pad seat and a staining roller which is configured on the ink pad seat in a rotating way, wherein the staining roller comprises a roller body with a hollow cavity and a color storing cushion layer which is sleeved outside the roller body; a shaft core of a shaft head at one end of the roller body is provided with a through hole running from the hollow cavity of the roller body to the outside of the roller body; a plurality of color through holes led to the color storing cushion layer are arranged on the wall of the hollow cavity of the roller body; and a color injecting opening is arranged on a seal seat and led to the hollow cavity of the roller body by the through hole of the shaft head at one end of the roller body.
