摘要： An image forming method begins with a first image transfer step for thermally transferring a first toner image from a first image carrier to a second image carrier contacting it. Subsequently, in a second image transfer step, the first toner image carried on the second image carrier and a second toner image newly formed on the first image carrier are thermally transferred to opposite sides of a recording medium substantially at the same time. Higher image transfer temperature is assigned to the second image transfer step than to the first image transfer step. An impurity collecting device is associated with a pair of registration rollers which stop the recording medium for a moment to thereby synchronize the recording medium to the toner image.
摘要翻译：图像形成方法从第一图像转印步骤开始，用于将第一调色剂图像从第一图像载体热转印到与其接触的第二图像载体。随后，在第二图像转印步骤中，基本上同时将携带在第二图像载体上的第一调色剂图像和新形成在第一图像载体上的第二调色剂图像热传递到记录介质的相对侧。与第一图像转印步骤相比，将更高的图像转印温度分配给第二图像转印步骤。一种杂质收集装置与一对定位辊相关联，该对准辊使记录介质停止片刻，从而使记录介质与调色剂图像同步。

摘要： An image transferring device of the present invention includes a first and a second intermediate image transfer body whose surfaces endlessly move while forming a nip in contact with each other. When a sheet nipped by the nip is being conveyed toward a side downstream of the nip in the direction in which the above surfaces move, a first toner image transferred from an image carrier to the second intermediate image transfer body via the first intermediate image transfer body beforehand is transferred to one side of the sheet. At the same time, a second toner image transferred from the image carrier to the first image transfer body beforehand is transferred to the other side of the sheet. One of the two intermediate image transfer bodies is less deformable than the other intermediate image transfer body in the direction of thickness.

摘要： An image forming apparatus of the present invention includes a first and a second intermediate image transfer belt contacting each other to form a nip for secondary image transfer. While the nip is heated, a sheet is passed through the nip to thereby transfer toner images respectively formed on the first and second belts to opposite surfaces of the sheet at the same time. The nip is sized such that image transfer and fixation can be effected at temperature higher than the melting point or the softening point of toner by 5° C. to 50° C.

摘要： A developing device develops a latent image electrostatically formed on an image carrier in a developing region to produce a corresponding visible image. The developing device includes a rotatable developer carrier for carrying a developer to the developing region and a charging device for forming small closed electric fields in the vicinity of the surface of the developer carrier. The developer is deposited on the surface of the developer carrier by the small closed electric fields. The developer carrier comprises a conductive base and dielectric bodies fixedly buried in recesses formed in the conductive base with each of the dielectric bodies having a predetermined cross-section which extends in a direction of a line normal to the surface of the developer carrier. Also, the developer carrier has a photoconductive surface which is charged by a charging device and selectively illuminated by an illuminating device to deposit a charge on the photoconductive surface which forms a great number of microfields on the photoconductive surface.
