A doctor blade assembly for an image forming device such as a laser printer includes a bracket to which foam is attached providing improved tolerances in the nip formed between the assembly and the doctoring media. The control unit keeps the relay switch in an off state if the temperature of the fixing member is equal to or more than a predetermined temperature when the fixing member has stopped rotation. Thereby the influences of a delay caused by the input circuit, which would not be able to be avoided in the prior art, can be avoided and thus the accurate internal clock signal can be generated. A driving unit drives the hauling unit based on the control signal. With such a configuration adopted, it is possible to provide a memory device capable of performing high speed reading while realizing a redundancy replacement. This is applicable to any rich structured data that should be mapped into search properties for a desktop search service.
