摘要： In an electrophotographic recording apparatus, toner images of different colors formed on a photosensitive belt are transferred in overlapping fashion to an intermediate transfer drum to form a color toner image and the color toner image is transferred to a secondary recording medium by means of a transfer unit and then fixed. The intermediate transfer drum includes an electrically conductive drum substrate and a dielectric layer whose resistance is adjusted to a predetermined range, and the drum substrate is connected to earth potential so that setting of an electric field for toner image transfer from the photosensitive belt may not interfere with setting of an electric field for toner image transfer by the transfer unit. Efficiencies of transfer at the two transfer sections can be improved to provide a color image of high quality and the apparatus can be reduced in size.
摘要翻译：在电照相记录装置中，形成在感光带上的不同颜色的调色剂图像以重叠的方式传送到中间转印鼓，以形成彩色调色剂图像，并且彩色调色剂图像通过转印单元转印到二次记录介质然后固定。中间转印鼓包括导电鼓基底和电阻调节到预定范围的电介质层，并且鼓基底连接到地电位，使得从感光带调色剂图像转印的电场的设定可能不会干扰通过转印单元设置用于调色剂图像转印的电场。可以改善在两个转印部分处的转印效率，以提供高质量的彩色图像，并且可以减小装置的尺寸。

摘要： In order to provide a magnetic recording medium having excellent electromagnetic conversion characteristics, a magnetic recording medium (10) is provided with a substrate (12), and a magnetic recording layer (20) formed on the substrate (12). The magnetic recording layer (20) is provided with a granular layer (32), i.e., a magnetic layer, including magnetic grains and a nonmagnetic material surrounding the magnetic grains in a section parallel to the main surface of the substrate.

In the histogram of such ratio, a half width at half maximum of the histogram is 0.6 or less and the variance of grain diameters of the magnetic grains in the section is 20% or less of the average grain diameter of the magnetic grains.
