A rendering device includes: a outline rendering unit that renders outlines of a character on a rendering area, based on outline data of the character; a specifying unit that specifies a data size of a variable which increases/decreases depending on a drawing direction of each of the outlines, when the rendering area where the outlines are rendered is scanned along predetermined scan lines; a variable storage unit that scans the rendering area where the outlines are rendered, for each of the scan lines, and stores the variable of the data size specified by the specifying unit, for each of pixels existing on the each of the scan lines; and a paint unit that specifies areas inside the outlines on the rendering area, based on the variable stored by the variable storage unit, and arranges pixels of a rendering color in the specified areas.
