Abstract

For better image quality of electrophotography, technologies which faithfully transfer toner images on an OPC or on an intermediate transfer member to transfer media, such as intermediate transfer members and papers, are demanded in the transfer process. Understanding the physics in the process, including various image degradation phenomena, is necessary for ensuring the fidelity, and therefore, fundamental technologies like visualization, measurement, and simulation play an important role in design and development for better image quality. For example, toner scatterings and non-uniformity of the image density, which are typical image degradation phenomena in the transfer process, have been investigated in detail by such fundamental technologies, and in recent printers, they are suppressed by design and development depending on the physics. In this article, some transfer technologies to suppress image degradations in practical use are reviewed, with studies on the image degradations by using fundamental technologies. And as a topic, Ricoh AC Transfer Technology, which realizes uniform images even on heavily textured papers, is introduced, and technology trends in the field of transfer process are discussed.
