Patent number: 6212338Abstract: Bidirectional communication is carried out between a toner bottle end communication device disposed in a toner bottle and a main body end communication device disposed in a device main body while the toner bottle is moved from a first position where the toner bottle starts being attached to the device main body to a second position where the toner bottle is completely attached. The CPU provided in the main body end communication device decides whether or not the information on the toner bottle received from the toner bottle end communication device matches the device main body, and notifies prior to toner refilling. If the toner bottle is not suitable, the CPU specifies a lower quality image forming condition under which operation conditions for the main charging device, exposure device, and fixing device are changed so as to produce an image of relatively low quality in comparison to normal quality.Type: GrantFiled: March 29, 2000Date of Patent: April 3, 2001Assignee: Sharp Kabushiki KaishaInventors: Hideaki Hagihara, Haruo Nishiyama, David Isner, Kenichi Nagata

Patent number: 6198900Abstract: A region with high resistance equal to the atmosphere is provided in a transfer roller. A discharge electrode capable of performing discharge between a base member and the discharge electrode is arranged within the region. When a predetermined electric potential is applied to the discharge electrode from a transfer power supply, the electric potential is separated and respectively applied to a first region in the transfer roller and a second region between the transfer roller and a photosensitive drum. At this time, since both the first and second regions are regions of high resistance, the electric potential applied to each region is equal, and therefore the electric field can never be concentrated in the second region. Moreover, since a predetermined electric field is formed in the first region, even when the transfer roller and photosensitive drum come into contact with each other, a transfer current can never collect in the contact.Type: GrantFiled: February 3, 1999Date of Patent: March 6, 2001Assignee: Sharp Kabushiki KaishaInventor: Shirou Wakahara
