摘要： It is intended to provide an image forming apparatus capable of conducting charge adjustment of post-transfer residual toner appropriately by securing a contact area of a temporarily-collecting member and an electrode, without applying excessive deformation load to the temporarily-collecting member. There are arranged a brush roller for temporarily collecting post-transfer residual toner, and an electrode of which inwardly-curved face being in contact with the brush roller in a toner charge apparatus. Thereby, charged-in-opposite-polarity toner, out of post-transfer residual toner, is collected by the brush roller, polarity of the toner is reversed to original polarity, and then, returned to a photosensitive drum. The inner face of the electrode, i.e., a contact face of the electrode and the brush roller is formed in an inwardly-curved face. Thereby, a large contact area and light pushing force of the electrode to the brush roller can go together.

摘要： To prevent image defects such as fog and irregularities caused by the accumulation of the oppositely charged toner by flying the toner toward a photoreceptor to compulsorily consume the toner even though the toner is oppositely charged toner having a small charged amount. A potential difference between the photoreceptor and the development roller is set at a value at which the normally charged toner on the development roller can be flown toward the photoreceptor in the development phase at the time of compulsorily consuming the toner, and this potential difference is set at a value at which the flown normally charged toner can be returned to the development roller in the recovery phase. A development duty and a frequency f are set in such a way that a time period in the development phase is larger than a time taken for the normally charged toner on the development roller to fly to a point located midway between the development roller and the photoreceptor and is smaller than a time taken for arriving at the photoreceptor, and a time period in the recovery phase is larger than a time taken before the normally charged toner arrived at the point located midway between the development roller and the photoreceptor arrives at the photoreceptor, returns to the development roller to beaten out the oppositely charged toner and the oppositely charged toner beaten out flies to the photoreceptor.
摘要翻译：为了防止由于相反充电的调色剂的积聚引起的图像缺陷，例如通过将调色剂朝向感光体飞行而强制消耗调色剂，即使调色剂具有相反电荷的带电量小的调色剂。感光体和显影辊之间的电位差被设定为在强制消耗调色剂时显影辊上的正常带电的调色剂能够在显影阶段中朝向感光体流动的值，并且设定该电位差在正常充电的调色剂可以在恢复阶段返回到显影辊的值。显影负荷和频率f被设定为使得显影阶段的时间段大于显影辊上的正常充电的调色剂飞行到位于显影辊和感光体之间的位置的时间并且小于到达感光体所需的时间，并且恢复阶段的时间段大于在正常充电的调色剂到达位于显影辊和感光体之间的位置到达感光体的时间，返回到显影辊，以殴打带相反电荷的调色剂，并将带相反电荷的调色剂扑灭到感光体中。

摘要： An image forming apparatus has a charging member opposed to an outer circumferential surface of a rotating object to be charged. The image forming apparatus has a voltage applying section for applying a pulsating voltage Vsp between the charging member and the object to be charged. The pulsating voltage Vsp is obtained by superimposing a voltage component of a direct current on a voltage component that periodically changes. The image forming apparatus is made to satisfy a relation of Vpp≦|Vth|, where Vpp is a peak-to-peak voltage value of the pulsating voltage Vsp and Vth is a charging start voltage value of the object to be charged. The relation prevents opposite charge from being imparted to residual toner on the object to be charged.

摘要： An image forming apparatus for forming an image with few defects even when making a copy from a copied image. When forming an image, a standard pattern is formed outside the image forming area in accordance with standard pattern data for color correction. When reading the image together with the standard pattern formed above, the color correction conditions for the image data are modified in accordance with the comparison result between the read standard pattern data and the standard pattern data for color correction. Copying is then performed on a copying paper.

摘要： In a digital full color copying machine, one pixel on a photoconductor is divided into four subdivided small pixels. Functions a-d are assigned to each subdivided small pixel. Functions a-d are linear functions with density data as a parameter. The slope of functions a-d becomes smaller in sequential order. Exposure data of the four subdivided small pixels is calculated according to the density data of a pixel and functions a-d to expose each subdivided small pixel. A peak can be established in the exposure amount distribution to form a deeper latent image. Accordingly, resolution and graininess of the halftone area are improved.
