Abstract: A paint roller handle construction (10) for delivering an on demand supply of paint to a porous paint roller (100). The handle construction (10) includes an elongated contoured hollow handle member (20) having a generally straight inboard end (21) and a generally U-shaped outboard end (22) which terminates in an elongated apertured axle element (30) having a generally bulbous inboard end (32), and a paint supply unit (12) that includes a pump member (40) disposed within and adapted to supply pressurized air both through the hollow handle member (20) and to a paint supply reservoir (50). Both pressurized air and pressurized paint are mixed within the bulbous inboard end (32) of the axle member (30) for distribution through the apertures (34) in the axle member (30) onto a porous paint roller (100).
