    • An image forming apparatus has an automatic power-off function for automatically shutting off a power source of the image forming apparatus when it is not operated for a predetermined time. A time until the automatic power-off function operates is made different in an ordinary standby mode and an interruption mode. The interruption mode is caused by an abnormality such as no paper. The time period in the interruption mode is made longer than the time period in the standby mode. The time period in the interruption mode is also made variable depending on the type of detected abnormality. The power-off time periods may be extended when an instruction is inputted via an operator. In addition, in an image forming apparatus having an original feeding device, a image forming mode is stored in memory and all the originals which have not been imaged will be ejected before the power is shut off in the interrupt mode.
    • 图像形成装置具有自动断电功能,用于在图像形成装置未被操作预定时间时自动关闭图像形成装置的电源。 直到自动断电功能运行的时间在普通待机模式和中断模式下不同。 中断模式是由无纸等异常引起的。 使中断模式下的时间段长于待机模式下的时间段。 中断模式中的时间段也根据检测到的异常的类型而变化。 当通过操作者输入指令时,断电时间可以延长。 此外,在具有原稿馈送装置的图像形成装置中,图像形成模式被存储在存储器中,并且在中断模式中断电之前,所有未成像的原稿将被弹出。
