20130308971 | DEVELOPER ACCOMMODATING UNIT, DEVELOPING DEVICE, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A developer accommodating unit includes: a developer accommodating member, provided with an opening for permitting discharge of a developer, for accommodating the developer; a sealing member including a connecting portion for being connected to the developer accommodating member so as to seal the opening; and an unsealing member for exposing the opening by moving the sealing member to peel the connecting portion from the developer accommodating member. The connecting portion includes a first connecting portion and a second connecting portion with respect to a longitudinal direction thereof. When the connecting portion is peeled from the developer accommodating member, the unsealing member is flexed so that the first connecting portion is peeled earlier than the second connecting portion. | 11-21-2013 |
20140072326 | UNIT, CLEANING UNIT, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A cleaning unit usable with an image forming apparatus includes a cleaning blade, supported by a frame and including a free end contactable to an image bearing drum, for removing a developer from the drum; a first seal provided between the frame and the blade by injection molding into the frame adjacent to a longitudinal end portion of the blade, the first seal being effective to prevent developer leakage; and a second seal provided between the drum and the frame in contact with the free end of the blade adjacent to the longitudinal end portion, wherein the first seal includes a seal portion contacting the blade, and a seat supporting the second seal, the seat being deformable to move the second seal to urge the second seal to the free end of the blade when the drum is mounted to the frame. | 03-13-2014 |
20140072335 | PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A process cartridge, wherein both in the case where the developing unit is at the contact position and in the case where the developing unit is at the separation position, a first regulating portion that the image bearing member unit has and a first regulated portion that the developing unit has, are engaged with each other, whereby the position in the axial direction of the image bearing member is regulated, wherein in the case where the developing unit is at the separation position, a second regulating portion and a second regulated portion, overlap each other in a direction perpendicular to the axial direction, and wherein in the case where the developing unit is at the contact position, the second regulating portion and the second regulated portion do not overlap each other in the direction perpendicular to the axial direction. | 03-13-2014 |
20140086620 | DEVELOPER ACCOMMODATING CONTAINER, DEVELOPING CATRIDGE, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A developer accommodating container for accommodating a developer includes: a toner seal member for unsealably sealing an opening of the developer accommodating container; an unsealing member, connected to an end portion of the toner seal member, for unsealing the opening by moving at least a part of the toner seal member; and an auxiliary unsealing member for assisting unsealing by changing a pulling direction of the toner seal member by the unsealing member. The auxiliary unsealing member includes a shaft portion or a projected portion. The shaft portion or the projected portion extends in a longitudinal direction of the developer accommodating container. | 03-27-2014 |
20140161483 | IMAGE FORMING APPARATUS AND CARTRIDGE - An image forming apparatus loadable with a cartridge includes a supporting member movable, carrying the cartridge, between an inside position and an outside position, the supporting member being provided with a first regulating portion to limit the cartridge in one of the longitudinal directions and a second regulating portion to limit movement of the cartridge in the other one of the longitudinal directions; a third regulating portion to limit the supporting member in the one longitudinal direction; and a fourth regulating portion to limit the supporting member in the other longitudinal direction; wherein the first, second, third and fourth regulating portions are all provided at the one longitudinal end portion side and outside an image forming region. | 06-12-2014 |
20150033888 | DRIVE TRANSMISSION APPARATUS AND IMAGE FORMING APPARATUS - A drive transmission apparatus in which, when immobilization of a preceding gear ( | 02-05-2015 |
20150042033 | SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS - A variable speed unit is driven by a drive unit to make a tooth-missing large gear of a sheet feed tooth-missing stage gear mesh with a small gear of an input stage gear rotating at a constant speed, to then rotate a rotating shaft of the feeding roller and a cam at a first speed to lift an intermediate plate. If a sheet stacked on the intermediate plate is pressed against the feeding roller, the variable speed unit makes a large gear of the input stage gear and a tooth-missing small gear of the sheet feed tooth-missing stage gear mesh with each other, so that the rotating shaft of the feeding roller is rotated at a second speed faster than the first speed to rotate the feeding roller at a fast speed. | 02-12-2015 |
20150139689 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a supporting member supporting multiple cartridges and movable between an inside position inside an apparatus main body and an outside position, in which the cartridges are supported arrayed in a direction of extracting the supporting member from the inside position to the outside position, with the multiple cartridges being detachably attachable at the outside position; a first cartridge; a second cartridge adjacent to the first cartridge; and a third cartridge adjacent to the second cartridge. The first cartridge has a greater protrusion amount from the supporting member compared to the second cartridge and the third cartridge, in a direction orthogonal to the extracting direction and to a longitudinal direction of the cartridges. When viewed from the orthogonal direction, the amount of overlapping between the first cartridge and the second cartridge is greater than the amount of overlapping between the second cartridge and the third cartridge. | 05-21-2015 |
