A cleansing composition containing the following components and : an ether carboxylate of Formula R1\u2014O\u2014n\u2014CH2\u2014COOX wherein \u2014R1 represents a linear or branched C4-C10 alkyl or alkenyl group, \u2014n represents a number from 0. By providing at least one ungrounded antenna and at least one ground antenna, there is low correlation between antennas resulting in a high diversity gain. A controller receives the detected voltage through an AD port and performs onoff control of the fuser to keep its temperature at a predetermined level. Wiring of the IC is grouped and integrated on the PLC substrate to achieve higher density and miniaturization of the optical module.
