Claims (1)
検知素子とを備えた定着部を有した複写機におい
て、緊急コピー可能時期を該温度検知素子によつ
て検知した熱ローラの温度に基いて決定し早期に
コピー可能状態に移行させる制御部を備えたこと
を特徴とする複写機。 In a copying machine having a fixing unit equipped with a heat roller and a temperature detection element that detects the temperature of the heat roller, an emergency copy possible time is determined based on the temperature of the heat roller detected by the temperature detection element. What is claimed is: 1. A copying machine characterized by comprising a control unit for quickly transitioning to a copy-enabled state.
