    Abstract: A toner supply device includes a toner storage, a supply opening, a toner conveyer, a toner supply opening, and an air passage. The toner storage stores toner. Through the supply opening, the toner is supplied to a developing device. The toner conveyer includes an area of space different from an area of space of the toner storage. The toner conveyer conveys the toner stored in the toner storage to supply the toner from the supply opening to the developing device. Through the toner supply opening, the toner is supplied from the toner storage to the toner conveyer. The air passage is at a position different from the toner supply opening. The air passage connects the toner storage to the toner conveyer so as to allow air flowing through the supply opening into the toner conveyer to be supplied to the toner storage through the air passage.

    Abstract translation: 调色剂供应装置包括调色剂储存器，供给开口，调色剂输送器，调色剂供给开口和空气通道。 调色剂存储器存储调色剂。 通过供给口，将调色剂供给到显影装置。 调色剂输送机包括与调色剂存储器的空间区域不同的空间区域。 调色剂输送机传送存储在调色剂储存器中的调色剂，以将调色剂从供给开口供给到显影装置。 通过调色剂供应开口，调色剂从调色剂储存器供应到调色剂输送机。 空气通道处于与调色剂供应开口不同的位置。 空气通道将调色剂储存器连接到调色剂输送机，以便使流过供给开口的空气进入调色剂输送机，以通过空气通道供应到调色剂储存器。

    Abstract: An electrical machine includes an exhaust fan and an exhaust port on which an optional device is mounted. The optional device includes a duct, an electric fan, and an air flow sensor. Through the duct, an exhaust gas from the exhaust port is guided. The electric fan draws in the exhaust gas flowing through the duct and discharges the exhaust gas into an atmosphere. The air flow sensor detects presence or absence of the exhaust gas flowing from the electrical machine. The air flow sensor includes an air path partitioned from an inside of the duct by a partition wall. The air path includes an exhaust gas and an exit port. The exhaust gas intake port includes an opening facing the exhaust gas. The exit port communicates with the atmosphere at a position outside the duct.
