    • A color image forming device includes a housing, a photosensitive unit, an exposing unit, at least three developing units, a transfer unit, and a fixing unit. The housing has a recording medium discharge opening for discharging recording media in a forward direction. The photosensitive unit includes a photosensitive belt with a photosensitive layer. The exposing unit exposes the photosensitive layer to form a series of latent images on the photosensitive belt. The developing units are provided in a forward portion of the housing, each including a different color developing agent for supplying developing agent to the photosensitive belt to develop corresponding latent images into visible images. The transfer unit transfers the visible images onto a recording medium. The fixing unit is provided in a rear portion of the housing unit, fixes the visible images onto the recording medium and transports the recording medium toward the discharge opening.

    • An image forming device includes a developer bearing member, a photosensitive member, a developing-bias applying portion, a pressing-force adjusting portion, and a density adjusting portion. The photosensitive member is disposed in contact with the developer bearing member. An electrostatic latent image is formed on the photosensitive member and developed by the developer supplied from the developer bearing member for forming a developer image. The developing-bias applying portion applies a developing bias to the developer bearing member. The pressing-force adjusting portion adjusts the pressing force between the developer bearing member and the photosensitive member. The density adjusting portion controls both the developing-bias applying portion and the pressing-force adjusting portion to adjust, based on adjustment of both the developing bias and the pressing force, an amount of developer in the developer image developed on the photosensitive member, thereby adjusting density of a developer image on a recording medium.
    • 图像形成装置包括显影剂承载部件,感光部件,显影偏压施加部分,按压力调节部分和密度调节部分。 感光构件设置成与显影剂承载构件接触。 在感光构件上形成静电潜像,并由用于形成显影剂图像的显影剂承载构件供给的显影剂显影。 显影偏压施加部分向显影剂承载部件施加显影偏压。 按压力调节部分调节显影剂承载部件和感光部件之间的按压力。 密度调节部分控制显影偏压施加部分和按压力调节部分两者,以便基于显影偏压和按压力的调节来调节在感光构件上显影的显影剂图像中的显影剂的量,由此 调节记录介质上显影剂图像的浓度。

    • A fixing device has a fixing unit and a temperature detection unit. The fixing unit includes a heat roller provided with a roller section and a heater section, and a pressure roller in pressure contact with the heat roller. These rollers are disposed in a protective cover. The roller section includes a base layer of aluminum formed into a hollow cylindrical shape, a black radiation layer, and a toner parting layer. The heater section is disposed in a hollow space of the base layer. In this heat roller, when heat is emitted from the heater section, and the heat is transmitted to the radiation layer via the base layer, greater amount of infrared radiation is emitted from the radiation layer than in the case of a heat roller that is not equipped with the radiation layer. The temperature detecting unit includes an infrared radiation sensor. Thus, even if a noise component is absorbed to some extent by locating the sensor at a distance from the heat roller on an outside of the protective cover, the temperature of the heat roller is detected accurately.
    • 定影装置具有定影单元和温度检测单元。 定影单元包括设置有辊部和加热部的加热辊以及与加热辊压接的加压辊。 这些辊子设置在保护罩中。 辊部分包括形成中空圆柱形状的铝基底层,黑色辐射层和调色剂分离层。 加热器部分设置在基层的中空空间中。 在该加热辊中,当从加热器部分发出热量,并且热量经由基底层传递到辐射层时,从辐射层发射的红外线辐射量比不是 配有辐射层。 温度检测单元包括红外线辐射传感器。 因此,即使通过将传感器定位在距保护罩外侧的加热辊一定距离处,某种程度的噪声成分被吸收,也能准确地检测出加热辊的温度。
