A method of configuring a wireless connection of an image forming apparatus via near field communication is provided. The method further includes conveying the sheet on the transport path so that the sheet contacts the reference surface at one position of the set, engaging the probe with the sheet at the one position to determine a measured sheet thickness value, and adjusting the measured sheet thickness value based on the runout value for the one position to obtain an actual sheet thickness value. The receiver combines the first and the second sets of energy values to determine a combined set of energy values. They are kneaded, and the EPDM rubber is vulcanized and molded. The base member is arranged at the bottom side of the bottom cover shell to provide power supply to the heater for producing heat that is transferred through the lower panel and the upper panel to heat the aromatic fluid in the fluid container. A shift capacitor is provided between a connection point of the first and second switching transistors and a connection point of the third and fourth switching transistors, and a holding capacitor is connected to the boosted output terminal OUT.
