摘要: A fixing device for forming a toner image formed on a recording medium includes a heat roller accommodating a halogen heater. The halogen heater includes a glass tube formed of transparent quartz and provided with a wall thickness of 0.8 mm or below to increase transmission thereof. The increased transmission reduces a heat loss ascribable to the glass tube at the time of warm-up of the fixing device. The heat roller has such a thermal capacity that it can be warmed up in 10 seconds or loss. The glass tube is filled with inactive gas whose major component is krypton or xenon. A tungsten filament accommodated in the glass tube has its diameter reduced in order to implement a color temperature of 2,500 K or above. An image forming apparatus using the fixing device is also disclosed.

摘要: A heating device of the present invention includes a main power source and an auxiliary power source implemented by a chargeable capacitor. A heater is made up of a main heating element that heats when supplied with power from the main power source and an auxiliary heating element that heat when supplied with power from the auxiliary power source. A charger charges the capacitor of the auxiliary power source when supplied with power from the main power source. A switch selectively causes the auxiliary power source to be charged or to feed power to the auxiliary heating element. A controller adjusts the power to be fed from the auxiliary power source to the auxiliary heating element.

摘要: An image forming apparatus includes an exhaust duct to guide air inside the image forming apparatus to an outside of the image forming apparatus. A positive ion generator emits a positive ion into the exhaust duct. A negative ion generator emits a negative ion into the exhaust duct. The negative ion generator is shifted from the positive ion generator in one of an air flow direction of the air moving inside the exhaust duct and a direction perpendicular to the air flow direction.

摘要: A fixing device includes an endless, rotatable fixing belt, a pressure rotator, a nip formation pad, a support, and a vibration repressor. The pressure rotator presses an outer surface of the fixing belt. The nip formation pad is disposed at an inner side of the fixing belt, to abut on the pressure rotator with the fixing belt interposed between the nip formation pad and the pressure rotator to form a fixing nip. The support is disposed at the inner side of the fixing belt, to support the nip formation pad. The vibration repressor is disposed between the nip formation pad and the support, to repress vibration of the nip formation pad.

摘要: In image processing, it is possible to suitably reduce density unevenness and graininess according to the ink used in printing. More specifically, when dividing multi-valued data and generating data for 2-pass multi-pass printing, in addition to divided multi-valued data for each of the two passes, divided multi-valued data that is common to the two passes is also generated. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each of the passes. Furthermore, when generating the quantized data, the division ratios used when generating the common data using the aforementioned multi-valued data division are set according to the colors of ink used in printing. By doing so, it becomes possible to suitably reduce density unevenness and graininess according to the colors used in printing.
摘要翻译: 在图像处理中,可以根据印刷中使用的油墨适当地减小浓度不均匀性和颗粒性。 更具体地说,当分割多值数据并产生用于2遍多遍打印的数据时,除了两次通过中的每一个的分割多值数据之外,还可以将两次通过的共同的分割多值数据 生成。 此外,该通用多值数据的量化数据反映在每个通过的量化数据上。 此外,当生成量化数据时,根据在打印中使用的墨的颜色来设定使用上述多值数据分割生成公共数据时使用的分割比。 通过这样做,可以根据印刷中使用的颜色适当地减小浓度不均匀性和颗粒性。
