    摘要： An ozone exhaust system in an image forming apparatus having a multiple number of process printing units, includes: exhaust ducts for exhausting ozone arising in the process printing units. In the ozone exhaust system, the exhaust ducts are mainly constituted of process printing unit's side exhaust ducts provided respectively along multiple charger cases and a main exhaust duct to which the process printing unit's side exhaust ducts are connected, and the process printing unit's side exhaust ducts are constructed so that the air current that flows into the charger cases and the air current that flows from the process printing unit's side exhaust ducts into the main exhaust duct are directed in the same direction.

    摘要： As a projection extending member is arranged adjacently to a projection, a sensor S1 produces an “ON” state output when an eccentric cam starts turning even in non-printing mode. The time from when the eccentric cam starts turning until sensor S1 changes its output from “ON” to “OFF” becomes longer when a new intermediate transfer belt unit is used than when a used intermediate transfer belt unit is used. The length of this time is measured so as to detect whether the intermediate transfer belt unit is brand-new or old.

    摘要翻译： 当突起延伸构件相对于突出部布置时，当偏心凸轮即使在非打印模式下也开始转动时，传感器S1产生“开”状态输出。 当使用新的中间转印带单元时，偏心凸轮开始转动直到传感器S1将其输出从“ON”改变为“OFF”的时间比使用中间转印带单元使用时的时间变长。 测量此时间的长度，以便检测中间转印带单元是全新的还是旧的。
