Title: Seamless belt containing fine particle
Inventor: ITO MASANORI
IPC: B29C41/04
Filed: 1985-03-05
Abstract: PURPOSE:To contrive an improvement in durability and strength, by making the Young's modulus of a cured coat of thermosetting resin which is of a raw material a value of more than a specific one. CONSTITUTION:Centrifugal molding is performed while a thermosetting resin solution into which fine particles are made to disperse is being heated by casting the same in the inside of a cylindrical mold. As for the thermosetting resin, such resin, whose Young's modulus of a cured coat C is more than 350kg/mm<2>, for example, polyimide resin, polyamide-inide resin, polyphenylene sulfide resin, polyether ether ketone resin, fluorine resin and aramid resin are used independently or as a mixture. As the majority electrically-conductive dust-size particles (b) are localized on the outside of a seamless belt due to a difference between centrifugal forces when specific gravity of electrically-conductive dust-size particles is larger than that of the thermosetting resin solution, it is possible to give electrical conductivity to only the outside of the same. On the contrary, when the specific gravity of the electrically-conductive fine particles is smaller than that of the thermosetting resin, it is possible also to give the electrical conductivity only to the inside.

Abstract: PURPOSE: To reduce the deviation in printing position or image blurring caused by the speed difference between the circumferential speed of a photoreceptor and the carrying speed of a paper sheet by making toner having different polarity on a photoreceptor have the same polarity as that of the photoreceptor with a pretransfer electrifier. CONSTITUTION: A high-potential part executes normal development with positively charged color toner having the polarity opposite to that of the photoreceptor 1 by a first developing device 4. Then, a low-potential part executes reversal development with negatively charged black toner having the same polarity as that of the photoreceptor 1 by a second developing device 5. After the development, the positively charged color toner and the negatively charged black toner which have the different polarity on the photoreceptor 1 are irradiated with a negative corona discharge by the pretransfer electrifier 6, to be negatively electrified, that is, obtain the same polarity as the photoreceptor 1.  Then, a paper sheet 15 is irradiated with a positive corona discharge by a transfer device 7 and electrified to the polarity opposite to the toner, that is the photoreceptor 1, to transfer the toner to the paper 15. At this time, the photoreceptor 1 and the paper 15 have the different polarity, to generate electrostatic attracting force and the deviation in the printing position or the image blurring caused by the speed difference between the photoreceptor 1 and the paper 15 can be reduced.
