Abstract: A paper feeder comprises an acquiring device, a driving roller, driven rollers, a driven roller supporter, a driver, and a controller. The acquiring device acquires thickness information on a sheet of paper. The driving roller rotates by being supplied with torque. The driven rollers rotate with the driving roller when in compressive contact with the driving roller. The driven roller supporter so supports the driven rollers that each of them can rotate under a different rotational load. The driver changes the position of the driven roller supporter relative to the driving roller. The controller selects one of the driven rollers on the basis of the thickness information and so activates the driver as to bring the selected roller into compressive contact with the driving roller.

Abstract: A fixing control section of a fixing apparatus according to the present invention includes an end section priority temperature control mode. In the end section priority temperature control mode, the fixing control section temporarily turns off a main heater heating a center section of a fixing roller among a plurarity of heaters disposed inside the fixing roller in a case where a surface temperature of the end section of the fixing roller has reached a preset upper-limit fixing temperature, even if the surface temperature of the center section of the fixing roller is lower than a preset fixing temperature. As a result, destruction of the fixing roller can be prevented by a simple arrangement in the fixing apparatus which includes a plurarity of the heaters disposed inside the fixing roller.

Abstract: A DLL circuit includes a delay line (CDL) (10) that delays a clock signal at a relatively coarse adjustment pitch, a delay line (FDL) (20) that delays the clock signal at a relatively fine adjustment pitch, and phase detecting circuits and counter control circuits that control delay amounts of the delay lines (10, 20). The counter control circuits control the delay line (10) by a linear search method, and control the delay line (20) by a binary search method. As a result, even when the number of bits of the count signal for adjusting the delay line (20) is increased, a delay amount can be determined at a high speed.

Abstract: 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.

Abstract translation: 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。
