摘要： An additional image is formed on a recording medium by filling a predetermined area including a punched portion or a stapled portion, in addition to an image which is to be formed originally, such as a text document. The additional image is formed with white developer or transparent developer. Since the thickness of the recording medium is increased by the white developer or transparent developer forming the additional image portion, the region around the punched portion or the stapled portion is reinforced and the recording medium is kept from being broken easily. When the image and the additional image are superposed, the superposition of the image and the additional image is avoided by either reducing the image or changing the position of the image to be formed.
摘要翻译：除了原本要形成的图像（例如文本文件）之外，还通过填充包括冲孔部分或装订部分的预定区域在记录介质上形成附加图像。附加图像由白色显影剂或透明显影剂形成。由于通过形成附加图像部分的白色显影剂或透明显影剂增加记录介质的厚度，所以加强了冲孔部分或缝合部分周围的区域，并且使记录介质容易地被破坏。当图像和附加图像叠加时，通过减少图像或改变要形成的图像的位置来避免图像和附加图像的叠加。

摘要： A sheet feeding device includes a sheet stacker and a locking mechanism. The sheet stacker has a stacking plate adapted for sheets to be stacked thereon. The sheet stacker is movable between a first position and a second position. In the first position, the sheet stacker is entirely housed in a casing, and, in the second position, is entirely exposed outside of the casing. The locking mechanism is adapted to lock the sheet stacker to the casing at each of the first and second positions. This arrangement prevents the sheet stacker as pulled out of the casing for sheet replenishment from being moved.

摘要： In an image forming apparatus of the present invention, an idle roller once stops rotating when a front edge of a sheet conveyed reaches the idle roller. The idle roller restarts rotating at such a timing that a front edge of a toner image on a photoreceptor and a front edge of an image writing position on the sheet are aligned with each other. Then, even if a rear edge of the sheet is still in the idle roller, the idle roller stops rotating when the front edge of the sheet is sandwiched between a transfer roller and the photoreceptor. By carrying out such operations, it is possible to avoid by a very simple way an occurrence of a slip phenomenon that is a phenomenon of slipping of the sheet with respect to the photoreceptor while suppressing a reduction in image quality as much as possible. In addition, it is also possible to surely secure a blank space formed at a rear edge portion of the sheet.
摘要翻译：在本发明的图像形成装置中，当传送的纸张的前缘到达空转辊时，空转辊一次停止旋转。空转辊重新开始旋转，使得感光体上的调色剂图像的前边缘和片材上的图像书写位置的前边缘彼此对准。然后，即使片材的后边缘仍然在空转辊中，当片材的前边缘夹在转印辊和感光体之间时，空转辊停止旋转。通过进行这种操作，可以通过非常简单的方式避免出现作为尽可能多地抑制图像质量降低的片材相对于感光体的现象的滑动现象。此外，还可以确保形成在片材的后边缘部分处的空白空间。

摘要： A developing device is provided with a developer vessel for storing therein a developer material composed of toner particles and carrier granules and a developer material supply section for gradually supplying a carrier developer including the carrier granules from above the developer vessel, wherein a discharge opening for discharging therethrough the developer material is formed on a side face of the developer vessel. When a tilt detection unit provided with the developing device detects the tilt of the developing device, an alarm lamp is set ON for sending a warning. In the meantime, the discharge opening is closed for preventing an excessive overflow of the developer material from the developer vessel.

摘要： An image forming apparatus includes a feeding portion, an image forming portion, a discharge portion, a paper transport path, a plurality of detection members, and a control portion. The image forming portion forms images on sheets of paper fed from the feeding portion. The path transports paper from the feeding portion to the discharge portion via the image forming portion. The detection members detect transport state of paper at respective locations on the path including the feeding portion, between the feeding and image forming portions, within the image forming portion, between the image forming and discharge portions, and the discharge portion. Upon detection of paper jam at any of the locations, the control portion displays, on an indicator, information identifying a location where the jam has occurred, and the image forming portion where paper is detected by the detection members, as locations of paper to be eliminated from the path.

摘要： A sheet feeder has a feed passage and includes feed roller pairs, sensors, and a controller. The feed roller pairs are arranged along the feed passage and feed sheets of paper in a feed direction along the passage by nipping the sheets. Each of the sensors is fitted at or near one of the feed roller pairs and senses a specified point on each of the sheets when the sheet is nipped by at least the associated roller pair. The controller includes a memory for storing reference feed timings as proper feed timings at each of which the specified points on the sheets should pass one of the sensors. The controller finds the real feed timing when each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair. When each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair, the controller finds the time difference between the associated reference feed timing and the associated real feed timing and controls, according to the found time difference, the feed speed at which the feed roller pair or pairs nipping the sheet feed it.
