What is claimed is: 1. An image forming device management system, comprising: a plurality of image forming devices; a central service station for providing a maintenance service for the image forming devices; and a communication device for connecting one of the image forming devices to the central service station via a communication network, wherein each of the image forming devices comprises: receiving means for receiving a non-resettable copy count and a remote message cycle, both transmitted to the image forming device by the central service station through the communication device, the copy count indicating a predetermined number of copy sheets with respect to a contract for use of the image forming device, the remote message cycle indicating a frequency at which the image forming device transmits a remote message to the central service station; first storage means for storing the copy count and the remote message cycle received by the receiving means; second storage means for storing a current copy count that is incremented every time an image formation of one copy sheet is performed by the image forming device; control means for setting the image forming device in a remote message enable state when a difference between the current copy count and the received copy count reaches an integral multiple of the remote message cycle; and remote message means for transmitting the remote message through the communication device to the central service station after the image forming device is set in the remote message enable state by the control means. 2. The system according to claim 1, wherein the remote message transmitted to the central service station by the remote message means includes a remote message purpose and the current copy count. 3. The system according to claim 1, wherein the copy count received by the receiving means indicates a predetermined number of copy sheets at a start of a block billing contract for use of the image forming device. 4. The system according to claim 1, wherein the copy count received by the receiving means indicates a predetermined number of copy sheets at an end of a block billing contract for use of the image forming device. 5. The system according to claim 1, wherein each of the image forming devices includes an operational display device, at least one of a copy count at a start of a block billing contract for use of the image forming device, a copy count at an end of the block billing contract, and the difference between the current copy count and the received copy count being displayed on the operational display device. 6. The system according to claim 1, wherein each of the image forming devices includes an operational display device, the difference between the current copy count and the received copy count being displayed on the operational display device. 7. A method of managing an image forming device, comprising: receiving a non-resettable copy count and a remote message cycle, both transmitted to the image forming device by a central service station through a communication device, the copy count indicating a predetermined number of copy sheets with respect to a contract for use of the image forming device, the remote message cycle indicating a frequency at which the image forming device transmits a remote message to the central service station; storing the copy count and the remote message cycle; storing a current copy count that is incremented every time an image formation of one copy sheet is performed by the image forming device; setting the image forming device in a remote message enable state when a difference between the current copy count and the received copy count reaches an integral multiple of the remote message cycle; and transmitting the remote message through the communication device to the central service station after the image forming device is set in the remote message enable state. 8. An image-forming device, comprising: means for forming an image; means for receiving a non-resettable copy count and a remote message cycle, both transmitted to the image forming device by a central service station through a communication device, the copy count indicating a predetermined number of copy sheets with respect to a contract for use of the image forming device, the remote message cycle indicating a frequency at which the image forming device transmits a remote message to the central service station; a memory configured to store the copy count and the remote message cycle, and to store a current copy count that is incremented every time an image formation of one copy sheet is performed by the image forming device; a processor configured to set the image forming device in a remote message enable state when a difference between the current copy count and the received copy count reaches an integral multiple of the remote message cycle; and means for transmitting the remote message through the communication device to the central service station after the image forming device is set in the remote message enable state.
