Title: Image forming method
Inventor: INAGAKI SANJI
IPC: G03G13/01
Filed: 1988-04-14
Abstract: PURPOSE:To prevent occurrence of color mixture at the part where toner of different colors is overlapped and to obtain an image with excellent color reproducibility by using toner which contains a low molecular weight polyolefin in either of developing stages. CONSTITUTION:When different potential latent images formed on a photosensitive body are developed with developer of different colors in order, either developing stage is carried out using the toner which contains the low molecular weight polyolefin. In both developing stages 4 and 5 several types of toner with different colors are overlapped and made to adhere to a high potential latent image part out of different potential latent images formed on the photosensitive body 1, and the result is transferred and fixed on a copying sheet 10. In this case, the low molecular weight polyolefin incorporated in either toner oozes out the surface of the sheet and forms a separation film on the interface between both toners. Therefore, the toners of different colors come to seldom mix with each other in a part of a copied image where they are overlapped and fixed. As a result, an image is visually reproduced with the color of the upper toner on the copying sheet, and an image with excellent color reproducibility is obtained.
