えられていることを特徴とする画像形成装置。[Scope of Claim for Utility Model Registration] A double-sided tray for a double-sided image forming mode that temporarily stores and re-feeds recording paper on which an image has been formed on one side, and a tray that processes the recording paper on which a toner image has been transferred to a certain level. When a fixing device fixes a toner image by heating with a fixing roller under pressure and an oil end detection signal of the release oil applied to the fixing roller of the fixing device,
In an image forming apparatus, the fixing control device is configured to inhibit the image forming operation after a set number of sheets have been executed. When a paper presence/absence detection signal is being applied and, in double-sided image forming mode, an oil end detection signal of the release oil of the fixing device and a paper presence signal from the paper detection means are simultaneously received, the image forming operation is performed for the set number of sheets. An image forming apparatus characterized by comprising a control means that enables control even after execution.
