A painting device, which is used for painting a plurality surfaces including curvature surfaces is invented. The painting devices have various shaped paint rollers that comprising the cone-shaped, V-shaped, I-shaped, wave-shaped, trapezoid-shaped, protrude-shaped, waist-drum-shaped and etc. These shaped rollers can be used singularly or by joining two or more together to form another shaped roller. Furthermore, the covered area of the roller can be changed by varying the length of the shaped rollers and the working surfaces of some of the rollers are covered by a flexible material that allows the length to be changed. These joined surfaces (corners), round rods, rectangular beams and other such structures can be finished efficiently with these rollers, respectively. The advantages of these paint rollers are painting complex structures that have multiple surfaces or various curvature surfaces with one stroke. Therefore, using the paint roller can provide a significant times savings with a high quality finish to complete the painting work. By the way, the paint rollers are suitable for automatic-driven roller. And a corresponding paint tray is introduced also.
