摘要:
An image forming apparatus including: an outputted image density control portion that forms a patch image and determines an outputted image density control condition based on a comparison result of the density of the patch image with a preliminarily set target value; a pixel count portion capable of counting the amount of image pixel at the time of image formation; a pixel count value accumulating memory portion that accumulates and stores the pixel count value; a toner supply portion; a toner supply amount measuring portion capable of measuring the amount of toner supplied to the developing device; a toner supply amount accumulating memory portion that accumulates and stores the toner supply amount; and a target value correcting portion that corrects the target value of the density of the patch image from the relation between a pixel count accumulating value and a toner supply amount accumulation value, is provided.
摘要(中):
一种图像形成装置,包括:输出图像浓度控制部分,其形成贴片图像,并且基于具有预先设定的目标值的贴片图像的浓度的比较结果确定输出的图像浓度控制条件; 能够对图像形成时的图像像素的数量进行计数的像素数计数部; 像素计数值累积存储器部分,其积累并存储像素计数值; 调色剂供应部分; 调色剂供应量测量部分,其能够测量供应到显影装置的调色剂的量; 调色剂供应量累积存储部分,其累积并存储调色剂供应量; 并且提供了根据像素计数累积值和调色剂供应量累积值之间的关系来校正色块图像的浓度的目标值的目标值校正部分。
