    摘要： A paper feeder is capable of minimizing abnormal noise produced at a separation pad during paper feed, without reducing the paper feed capability, for use in an image forming apparatus using the same. Buffers are mounted on the separation pad. This arrangement ensures that, when a stick-slip condition occurs between the paper and separation pad during paper feed, and the separation pad is vibrated by the paper, the buffer vibrates so as to dissipate the vibration energy of the separation pad, with the result that the vibration of the separation pad is minimized, thereby to reduce any abnormal noise.

    摘要： A driving force transmission device superior in reliability with suppressed rotation fluctuation. The driving force transmission device has gearing reception portions, three arm portions and a press member. The gearing reception portions are formed in the inner circumference of a rotor. The arm portions extend from a shaft radially. The arm portions can be elastically deformed. The arm portions have engagement tooth portions for transmitting a driving force of the shaft to the rotor. The press member presses the rotor to bend the arm portions in the direction where the rotor is pressed. In that state, the gearing reception portions gear with the engagement tooth portions.

    摘要： An image formation apparatus is disclosed. The image formation apparatus includes a fixing unit whose heater temperature is controlled to be in a non-offsetting range so that no offset is produced, the non-offsetting range being defined for each different paper thickness. Nip time remains constant even when the thickness of the paper to be printed on next is changed. Printing is suspended until the heater temperature, approaching the non-offsetting range, reaches an inconspicuous offset range on either side of the non-offsetting range, inconspicuous offset being produced if printing is performed in the inconspicuous offset range.

    摘要翻译： 公开了一种图像形成装置。 图像形成装置包括将加热器温度控制在非偏移范围内的定影单元，使得不产生偏移，为每个不同纸张厚度定义非偏移范围。 即使当下次要打印的纸张的厚度改变时，间隔时间也保持恒定。 打印被暂停直到接近非偏移范围的加热器温度在非偏移范围的任一侧达到不明显的偏移范围时，如果在不显着的偏移范围内执行打印，则产生不显着的偏移。
