PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of reducing power consumption necessary for heat fixing of a toner image in a fixing unit.SOLUTION: An image forming apparatus 1 includes a transfer unit 3, a fixing unit 4, and a heat storage unit 7. The transfer unit 3 forms a toner image on a print target material S. The fixing unit 4 heat-fixes the toner image formed on the print target material S on the print target material S. The heat storage unit 7 includes a heat storage material 25 made of a phase change material that emits heat in the course of phase change from liquid to solid. The heat storage unit 7 stores the heat in the fixing unit 4 in the heat storage material 25, and releases the heat stored in the heat storage material 25 to the print target material S conveyed from the transfer unit 3 to the fixing unit 4. With this configuration, the temperature of the print target material S carried into the fixing unit 4 can be increased by using the heat in the fixing unit 4.

Abstract:
PROBLEM TO BE SOLVED: To efficiently produce a model for performing physical phenomenon analysis in a coupled manner. SOLUTION: Information on cross sections at a plurality of positions of different given one-dimensional displacements regarding an analysis object is acquired as two-dimensional image data on used materials or materials associated with the positions in the respective cross sections. Used materials or materials for respective elements generated by mesh division of the analysis object are identified using the two-dimensional image data. Distribution information on given physical quantities of cross sections at a plurality of positions of different given one-dimensional displacement regarding the analysis object is generated as contour graphic data in the respective cross sections. As at least a part of the boundary condition or the load condition of the physical phenomenon analysis, the physical quantity is associated with each element generated by the mesh division or each node generated by each element by using the two or more pieces of contour graphic data.
