    Abstract: An image forming apparatus includes: an image forming section including a light exposure section configured to expose an image bearing member to light to form an electrostatic latent image, the image forming section being configured to form a toner image on the image bearing member, and to form an image on a recording sheet by transferring the toner image onto the recording sheet; an estimation section configured to estimate a density lowering position on the basis of image data of an image formed by the image forming section, the density lowering position being a position where decrease in image density relative to a predetermined image density is caused in the image; and a control section configured to increase a light exposure amount at the density lowering position estimated by the estimation section on the image bearing member to an amount greater than a predetermined light exposure amount.

    Abstract translation: 一种图像形成装置，包括：图像形成部，包括曝光部，被配置为将图像承载部件曝光以形成静电潜像，所述图像形成部构造成在所述图像承载部件上形成调色剂图像， 通过将调色剂图像转印到记录纸上形成记录纸上的图像; 估计部分，被配置为基于由图像形成部分形成的图像的图像数据来估计浓度下降位置，浓度下降位置是图像中引起相对于预定图像浓度的图像浓度降低的位置; 以及控制部，被配置为将由图像承载部件上的估计部估计的浓度降低位置处的曝光量增加到大于预定曝光量的量。
