Abstract: PURPOSE: To obtain an image forming device by which a clear image is obtained by using an intermediate transfer body whose transfer efficiency is excellent and which is constituted so that filming is prevented from occurring by specifying relation between the solubility index of binding resin in a coating layer and the solubility index of additive in the coating layer. CONSTITUTION: The intermediate transfer body 20 is driven to be rotated at an identical circumferential speed to a photoreceptor drum 1. The transfer body 20 is constituted of a pipe-like core bar 100 being a supporting body and the coating layer 101 formed on the outside circumferential surface of the core bar 100. Then, the image forming device is provided with the transfer body 20 having the coating layer 101 and an image carrier 1 for transferring the image on the transfer body 20. Besides, the relation between the solubility index SP1 of the binding resin in the layer 101 and the solubility index SP2 of the additive in the layer 101 is defined as |SP1-SP2|<=4.  Since the binding resin and the additive being in such relation are provided with high affinity, the additive does not flocculate in the binding resin and it uniformly exists extending over the whole layer nearly in a single grain state.

Filed: 1988-12-27
Abstract: PURPOSE:To prevent an accident where a master document is rewritten by mistake by setting the status information for each document and producing a warning when the corresponding document is updated in the case the set status information shows the master document. CONSTITUTION:When the document status information is set at a document file stored in an external memory 6, an operator points out a document to which the document status information is set. Then the status information to be set is designated and it is judged whether the pointed document is equal to a master document or not. If not, the general document status information is produced. If so, the master document status information is produced. Then the document status information is written into the designated document file. When the document is stored again, the document status information is checked. Then a warning message is displayed at a display part 4 when the master document is confirmed. Thus an instruction of the operator is waited for. Thus it is possible to prevent such a mistake where the master document is rewritten by mistake.
