Non-uniform charged potential of a surface of a photosensitive member is suppressed even when a temperature of a charging member newly mounted to an image forming apparatus by exchange is lower than a temperature inside the image forming apparatus. The ASR system and method can be used with a mobile device that is used in a communications network. The computed interference levels may be used to scale the corresponding data portions for subsequent processing. The molecules of the dispersing agent bind to the dissimilar components to overcome same-component attraction, thereby allowing the dissimilar components to form multicomponent nanoparticles. Within the outer housing is a generally cylindrical inner housing extending between and secured to the top and bottom of the spherical outer housing. In one embodiment, the guard interval length is selected based on a relationship between a selected coherence bandwidth and a RMS delay of the communication channel.
