1. An information storage device for an image forming apparatus, comprising at least two communication interfaces, at least two storage units, a detection unit, a first control unit and a second control unit, wherein
the communication interfaces configured to connect with a controller in the image forming apparatus, in the state that the communication interfaces are connected with the controller, set up a communication path between the first control unit and the controller; the storage units are arranged in accordance with the communication interfaces and configured to store variable information and backup information of an image forming cartridge in the image forming apparatus, in which the variable information at least includes first product information and image forming change information, and the backup information at least includes initial state information of the image forming cartridge; the detection unit connected with each foregoing communication interface and configured to detect the state of each foregoing communication interface and generate a first trigger signal and a second trigger signal when determining and acquiring that one communication interface is connected with the controller; the first control unit respectively connected with each foregoing storage unit and the detection unit and configured to acquire the variable information in the storage unit corresponding to the communication interface connected with the controller when receiving the first trigger signal, send the variable information to the controller, and send updated image forming change information sent by the controller through said communication interface to the storage unit corresponding to said communication interface so that the information can be stored into the storage unit; and the second control unit respectively connected with each foregoing storage unit and the detection unit and configured to at least rewrite the image forming change information in the storage unit corresponding to the communication interface disconnected with the controller into the backup information when receiving the second trigger signal. |
