摘要： A transfer device includes a holding body, a transfer body, and a setting portion. The holding body holds multiple layers including a base layer formed of a toner having a mass larger than a threshold. The toner is electrically charged by a charging device. The transfer body transfers the layers on the holding body to a recording medium. The setting portion sets the charging device so that the charging device electrically charges a toner immediately after being transferred to the holding body with a larger amount of electric charges when the base layer is located uppermost on the holding body, than when the base layer is located other than uppermost on the holding body.

摘要： An image forming apparatus includes a photosensitive drum, a developing device, a primary transfer part, a droplet ejecting unit and a controller. On the photosensitive drum, an electrostatic latent image is formed. The developing device forms a toner image by causing a developing agent to adhere to the electrostatic latent image. The primary transfer part transfers the toner image onto an intermediate transfer belt. The droplet ejecting unit ejects droplets onto the toner image on the photosensitive drum after forming the toner image on the photosensitive drum and before transferring the toner image to the transfer member. The controller controls an ejection area of the droplet ejecting unit in accordance with image information of the toner image.

摘要： The cleaning unit cleans the surface of the image carrying body after transfer of the toner image onto an image transfer object. The post-transfer neutralization unit is disposed between the transfer unit and the cleaning unit, and neutralizes electrical charge of the surface of the image carrying body after transfer. The first control unit controls neutralization light intensity of the pre-transfer neutralization unit such that a dark potential (V0 potential) of a non-image region on the image carrying body after pre-transfer neutralization is higher by 50 to 150 V than a bright potential (VL potential) of a solid image region. The first setting operating unit allows for an increase and decrease in the neutralization light intensity of the pre-transfer neutralization unit based on a status of an output image.

摘要： An image forming apparatus includes a PTC and a toner concentration sensor that are disposed adjacent to and downstream of a fourth image forming unit. The PTC and the toner concentration sensor are opposed to an intermediate transfer belt. A counter roller is opposed to the PTC across the intermediate transfer belt. The counter roller moves to, during the toner concentration detection, a position opposed to the toner concentration sensor across the intermediate transfer belt. Compared to the PTC and the toner concentration sensor each having a counter roller, less rollers may be provided, thereby reducing degradation of the intermediate transfer belt due to wear.

摘要： A developing device includes a photosensitive member having a surface on which a visible image is formed and a developing member to feed a developer to the photosensitive member, and an image forming apparatus having the developing device. The photosensitive member includes a developing region, to which the developer is transmitted by the developing member, and a transfer region, from which the developer of the photosensitive member is transmitted to a recording medium. A redistributing unit is disposed between the developing region and the transfer region, to redistribute the developer present on the photosensitive member. When developing a solid image and a halftone image in sequence is desired, even if a portion of the developer for use in development of the halftone image is prematurely transmitted to the photosensitive member, the redistributing unit can redistribute the transmitted developer so as to use the transmitted developer to develop the halftone image, resulting in a reduction in likelihood of image defects.
