A rendering device includes a temporary memory (13, 14), plural rendering processors (11, 12), and a rendering controller (15). The temporary memory (13, 14) stores one or more rendering instructions and rendered results for the one or more rendering instructions in association with each other. The plural rendering processors (11, 12) each perform rendering processing in accordance with a rendering instruction, store, in a case where one or more similar rendering instructions exist for pages for which rendering processing was consecutively performed, the one or more rendering instructions and rendered results in association with each other in the temporary memory (13, 14), and read and use, in a case where rendered results associated with one or more rendering instructions for rendering are stored in the temporary memory (13, 14), the rendered results associated with the one or more rendering instructions. The rendering controller (15) controls assigning a given rendering instruction to a corresponding one of the rendering processors (11, 12) and causing the corresponding one of the rendering processors (11, 12) to perform rendering processing, calculates the usage rate of rendered results stored in the temporary memory at a predetermined timing, and performs switching of an assigning method for assigning a rendering instruction in a case where the usage rate is lower than a predetermined threshold.
