    摘要： An image forming apparatus capable of reducing damage in a fixing section and printing a high-quality image on a sheet at low cost without reducing productivity. A sheet shifting mechanism is arranged upstream of a transfer roller and moves the sheet in a sheet lateral direction orthogonal to the sheet conveying direction. In order to change a position at which a sheet passes through a fixing roller, the sheet shifting mechanism is controlled for every conveyance of a predetermined number of sheets, whereby sheet movement in the sheet lateral direction is controlled. A correction amount for an error due to sheet shifting by the sheet shifting mechanism is stored for each of sheet shift positions. An image forming position in the sheet lateral direction of a photosensitive drum is shifted on the basis of the sheet shift position and the stored correction amount.

    摘要翻译： 一种图像形成装置，其能够降低定影部的损伤，并且以低成本在片材上印刷高质量的图像而不降低生产率。 片材移动机构设置在转印辊的上游，​​并使片材沿与片材输送方向正交的片材横向方向移动。 为了改变片材通过定影辊的位置，对于预定数量的片材的每次输送控制片材移动机构，由此控制片材横向方向上的片材移动。 对于每个片材移位位置存储由于片材移位机构的片材移位引起的误差的校正量。 感光鼓的纸张横向方向上的图像形成位置基于纸张偏移位置和存储的校正量而偏移。

    摘要： An image forming apparatus that can realize an image having adequate image quality, density and color, without provoking excessive consumption of a developer and reduction in productivity. Image formation is performed by forming a latent image on an image carrier based on image information, then developing and transferring the latent image. An image for adjustment on a portion is formed other than a portion on which the latent image is formed on the image carrier. The density of the image for adjustment is detected. Image density is adjusted based on the density of the detected image for adjustment. Image formation control is executed whereby density is adjusted when an image is formed. A printing rate that indicates the percentage of the image formation to a sheet used for image formation is calculated. When the printing rate is determined to be within a set range, the image formation control is executed at a set frequency. On the other hand, when the printing rate is determined to be outside the set range, the set frequency is changed and the image formation control is executed.
