To provide a paint storage container for a roller-type painting tool and a tool container, which are easy to handle during work on a roof and on an inclined surface and can achieve high work efficiency.

The storage container S9 keeps a container body Y9 supported in a controllable and fixable manner by a stabilizing leg A9, so that the storage container S9 can be placed so as to turn horizontal even when placed on an inclined surface. The front platform A51 and the back platform A52 of the stabilizing leg A9 provide support, and their support is controlled so the platform ground contact portion a62 closely contacts the inclining surface and also allows an anti-slip tool a81 for the platform ground contact portion to adhere to or attach to the platform ground contact portion a62 so that the storage container S9 can be placed on an inclined surface with no worry. An inner container and a pressing board are stored in the container body Y9 to form a brush rest space in a corner of the inner container so that the brush handle does not soak in the paint when the brush falls into the paint in the paint storage container S91.
