The purpose of the present invention is to provide a backup memory management system capable of indicating any misuse of data in a backup memory and imposing an appropriate sanction. It is preferable that at least a part of the conductive filler has protrusions. Source files representing content to be included as part of the fax message are stored to a shared storage area accessible by imaging systems and fax processing resources. The activation signal is transmitted based on a comparison of an activating energy level for each pulse position in a pulse stream with the energy values in the row of energy values.
