| 399025000 | Process cartridge | 9 |
| 20080304837 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD THEREOF - An image forming apparatus including an image forming unit which comprises a cartridge having a toner therein to form an image and a controller to control the image forming unit to increase a density of the image to be formed, if it is determined that a standard of the cartridge does not meet a usage requirement. | 12-11-2008 |
| 20090324261 | Image forming apparatus - An image forming apparatus is provided with an image forming portion for forming an image according to image information; an image forming unit arranged to be detachable and integrally including the image forming portion; a developer container arranged to be detachable for supplying developer to the image forming portion; and a blocking member for blocking developer from being supplied from the developer container to the image forming portion. | 12-31-2009 |
| 20110013916 | IMAGE FORMING APPARATUS, PROCESS UNIT CARTRIDGE, AND METHOD OF MANAGING REPLACEMENT LIFE OF PROCESS UNIT CARTRIDGE - An image forming apparatus includes: a process unit cartridge including an IC chip memory configured to store a set value table in which a set value as the replacement life of a process unit cartridge and a present value as the number of times of reuse are stored; a reader writer configured to read data from and write data in the IC chip memory; and a control unit configured to compare the set value and the present value readout from the IC chip memory and cause, when the present value exceeds the set value, a display unit to display indication that replacement is necessary. | 01-20-2011 |
| 20130039668 | IMAGE FORMING APPARATUS - An image forming apparatus includes an information rewrite unit that rewrites information stored in a storage if an empty detector detects that a toner container is empty and the toner container is at least allowed to be released, and then if the empty detector detects that the toner container is not empty. | 02-14-2013 |
| 20130251382 | LUBRICANT SUPPLYING DEVICE, IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE - A lubricant supplying device used with a solid lubricant, includes a supplying member to supply lubricant taken from the solid lubricant to an object to be supplied with the lubricant, and a remaining amount detecting section to detect a remaining amount of the solid lubricant becoming below a predetermined value. A detection of the remaining amount of the solid lubricant is executed when an operation to supply the lubricant to the object to be supplied with the lubricant stops. | 09-26-2013 |
| 20130272726 | IMAGE FORMING APPARATUS - An image forming apparatus, including a control portion configured to control a process condition for image formation, wherein the control portion changes the process condition for image formation when, in a case where a developing unit having a developer amount smaller than a predetermined amount is removed from a main body of the image forming apparatus, the developing unit removed is remounted to the main body of the image forming apparatus. | 10-17-2013 |
| 20140093257 | IMAGE FORMING APPARATUS - The present invention provides an image forming apparatus including a moving member configured to support a first process cartridge and move the first process cartridge to a position for forming an image, and a detection unit configured to detect a state of a second process cartridge, in which the moving member holds the detection unit. | 04-03-2014 |
| 20150370209 | Imaging Cartridge Circuit Board Mounting Pads - A consumable imaging unit has a hopper unit having a developer roller and a wastebin unit having a photoconductive drum. The developer roller contacts the photoconductive drum, forming a nip between the developer roller and the photoconductive drum, when the wastebin unit and the hopper unit are installed in an imaging machine. A first circuit board mounting pad located on the consumable imaging unit receives a first circuit board adapted to communicate a first set of required data and a second circuit board mounting pad located on the consumable imaging unit receives a second circuit board adapted to communicate a second set of required data. The consumable imaging unit also has a handle located in the center of an end of the consumable imaging unit, a planar member for guided movement by a slot in said imaging machine, and a torque tab receptacle adapted to receive a torque tab thereby limiting lateral movement between the hopper unit and the wastebin unit. | 12-24-2015 |
| 20170235268 | IMAGE FORMING APPARATUS HAVING PROCESS CARTRIDGE, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM | 08-17-2017 |
