Publication number: 20090110433Abstract: A system and process for emptying excess toner from repaired or remanufactured laser printer toner cartridges, for use in both magnetic toner and non-magnetic toner after the cartridge has been assembled and post-assembly tested. The removal of excess toner from the cartridge prevents the cartridge from “sweating”, i.e., leaking toner out from the developing roller section of the cartridge and into the shipping packaging box during shipping and storage.Type: ApplicationFiled: October 27, 2007Publication date: April 30, 2009Inventor: Jesus Gonzalez Perez

Patent number: 7522857Abstract: The object is to provide a toner which can be smoothly replenished by a toner replenishing device using a powder pump even when the toner contains a releasing agent, and an image forming apparatus using the toner. There is provided a toner, which comprises a binder resin, a colorant and a releasing agent, has a dynamic friction coefficient of 0.15 to 0.35, and is replenished by the toner replenishing device having a powder pump configured to automatically supply the toner and a toner container arranged in conjunction with the powder pump so as to develop a latent electrostatic image on a image bearing member.Type: GrantFiled: September 16, 2005Date of Patent: April 21, 2009Assignee: Ricoh Company, Ltd.Inventors: Kumi Hasegawa, Mitsuo Aoki, Hyo Shu, Minoru Masuda, Tomoko Utsumi
