    • There is provided an image forming apparatus which is capable of operating in a stable condition and in an efficient manner by omitting automatic adjustment in the case where there is no necessity of carrying out the automatic adjustment when the image forming apparatus returns from a power-saving mode to a normal mode. A CPU shifts the operation mode of the image forming apparatus to a power-saving mode in which power consumption is saved. The CPU detects at least one of a status of the image forming apparatus before the operation mode is shifted to the power-saving mode and a status of the image forming apparatus in the power-saving mode. The CPU determines the contents of a return process executed when the operation mode returns to a normal mode from the power-saving mode, according to the detected status of the image forming apparatus.
    • 提供了一种图像形成装置,其能够在图像形成装置从省电状态返回的情况下不需要进行自动调整的情况下通过省略自动调整而以稳定的状态和有效的方式动作 模式切换到正常模式。 CPU将图像形成装置的操作模式转换为省电省电模式。 在操作模式转换到省电模式之前,CPU检测到图像形成装置的状态中的至少一个以及处于省电模式的图像形成装置的状态。 CPU根据检测到的图像形成装置的状态,确定在从省电模式返回正常模式时执行的返回处理的内容。

    • There is provided an image forming apparatus which is capable of securing a time period for measuring the base reflected light quantity required for the base correction, and at the same time, reducing a time period required for the entire image density control. An image forming unit includes an image carrier disposed to be exposed to light to have a latent image formed thereon, an electrostatic charger that charges the image carrier to a predetermined polarity, a developing device that visualizes the latent image formed on the image carrier to form a visible image, and an endless belt onto which the visible image is transferred. A CPU controls the image forming unit to form predetermined detection patterns on the endless belt. The detection patterns and the quantity of reflection light from the endless belt are detected. The CPU corrects the detected detection patterns based on the detected quantity of reflection light. One of the image forming conditions is adjusted by the CPU, based on the corrected detection result of the detection patterns. Another one of the image forming conditions is adjusted by the CPU. The detection of the quantity of reflection light from the endless belt is carried out in timing synchronous with the adjustment of the other image forming condition.
    • 提供了一种图像形成装置,其能够确保用于测量基准校正所需的基底反射光量的时间段,并且同时缩短整个图像浓度控制所需的时间段。 图像形成单元包括设置为暴露于光以形成其上的潜像的图像载体,将图像载体充电至预定极性的静电充电器,使形成在图像载体上的潜像可视化的显影装置,以形成 可见图像和可移动的可见图像的环形带。 CPU控制图像形成单元以在环形带上形成预定的检测图案。 检测来自环形带的检测图案和反射光的量。 CPU基于检测到的反射光量校正检测到的检测图案。 基于校正的检测图案的检测结果,通过CPU调整图像形成条件中的一个。 另一个图像形成条件由CPU调整。 来自环形带的反射光量的检测在与其他图像形成条件的调整同步的定时中进行。
