摘要： An image generating apparatus is provided which can maximize the throughput without causing thermal damage of the fusing components. It determines a sub-thermistor temperature threshold value for switching small size paper feed intervals in response to a sub-thermistor initial temperature. It supplies a heating body with current for heating, and starts feeding recording mediums at the feed interval determined by a feed interval initial value. It makes a successively conveyed paper count. Every time the successively conveyed paper count reaches a paper count threshold value, it performs the switching control of the sub-thermistor temperature threshold value. If the sub-thermistor temperature exceeds the threshold value while the recording medium is passing through the fusing apparatus, it carries out the switching control of the feed intervals. In another mode, it prevents the extension of the paper feed interval of the paper conveyance during a specified paper count null.

摘要： It is an object of the preset invention to prevent jamming with small-sized print materials without disturbing an image located at a trailing end of a print material. An image forming apparatus has a photosensitive drum that carries a toner image, a transfer device which can apply a transfer bias to the transfer roller to transfer the toner image to a print material passing through the transfer nip portion, and a control device for controlling a transfer bias set value set in order to apply a predetermined transfer bias to the transfer roller. The control device switches a first transfer bias set value to a second bias set value smaller than the first transfer bias set value while the print material is passing through the transfer nip portion, in order to change the transfer bias applied to the transfer roller.
摘要翻译：本发明的一个目的是防止小尺寸印刷材料的干扰，而不会影响位于打印材料后端的图像。图像形成装置具有携带调色剂图像的感光鼓，可以向转印辊施加转印偏压以将调色剂图像转印到通过转印辊隙部分的印刷材料的转印装置，以及控制装置设定转印偏压设定值以便向转印辊施加预定的转印偏压。当打印材料通过转印夹持部分时，控制装置将第一转印偏压设定值切换到小于第一转印偏压设定值的第二偏置设定值，以便改变施加到转印辊上的转印偏压。

摘要： The present invention relates to an image forming apparatus comprising a heater heating a recording material for fixing a transferred toner image to the recording material at a transfer portion, a fixing unit having an overheat preventive device or overheat preventive devices for preventing the heater from overly heated and a plurality of recording material sensors for detecting existence of the recording material on the conveyance route or confirming passage of the recording material. A part or all of the overheat preventive devices are placed at an area sandwiched between any two planes which are perpendicular to a conveyance surface of the recording material and are extending parallel in the conveyance direction in passing the plurality of the recording material sensors.
