20100051426 | IMAGE FORMING APPARATUS - Disclosed in an apparatus in which an actuating member provided for an opening and closing member actuates a switch provided for a main body of the apparatus. The apparatus includes a protecting member protecting the switch and a restricting member restricting an object entering an opening of the protecting member. The restricting member has an opening smaller than the opening of the protecting member. The restricting member is movable in the direction intersecting the direction in which the actuating member passes through the opening of the restricting member. The opening of the restricting member is reduced in size to prevent an accidental operation while being insusceptible to a space in the apparatus or deformation of the apparatus. | 03-04-2010 |
20120057901 | IMAGE FORMING APPARATUS - The invention provides an image forming apparatus, having: an apparatus main body; a fixing unit fixing an image onto a recording material at a fixing nip portion, the fixing unit including a pressure applying portion applying a pressure to the fixing nip portion and a pressure releasing portion releasing the pressure; an opening/closing member disposed in the apparatus main body; an engaging portion engaging with the pressure releasing portion of the fixing unit in a state of being mounted to the apparatus main body for moving the pressure releasing portion, the engaging portion moving in conjunction with an opening/closing action of the opening/closing member; and a phase adjusting portion adjusting a phase of the pressure releasing portion to a phase of the engaging portion when the opening/closing member is opened, in conjunction with a mounting action of the fixing unit to the apparatus main body. | 03-08-2012 |
20120148273 | IMAGE FORMING APPARATUS - An apparatus is capable of switching between a mode in which a first resistance heating element and a second resistance heating element are connected in series and a mode in which they are connected in parallel. When a temperature increase rate detected by a temperature detection unit is smaller than a threshold rate although a current detected by a current detection unit is greater than a threshold current, a notification of a failure is issued. | 06-14-2012 |
20120242029 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - In order to provide a sheet conveying apparatus and an image forming apparatus capable of alleviating a bumping noise generated between a sheet and an inner guide member when the sheet passes through a curved sheet conveying path, a pair of intermediate conveying rollers is arranged in positions corresponding to both lateral sides in a width direction of the feeding roller and subsidiary feeding roller in a sheet conveyance direction. In addition, the subsidiary intermediate conveying roller abuts on the intermediate conveying roller with an inclination such that the sheet conveyance force is directed to the center of the sheet conveying path in a width direction. As a result, the sheet makes contact with the inner guide member of the facing guide member of the sheet conveying path by undulating the sheet in a width direction when the sheet is extracted and conveyed by the pair of intermediate conveying rollers. | 09-27-2012 |
20140294416 | IMAGE FORMING APPARATUS - An apparatus is capable of switching between a mode in which a first resistance heating element and a second resistance heating element are connected in series and a mode in which they are connected in parallel. When a temperature increase rate detected by a temperature detection unit is smaller than a threshold rate although a current detected by a current detection unit is greater than a threshold current, a notification of a failure is issued. | 10-02-2014 |
20140348548 | DEVELOPER CONTAINER, DEVELOPING DEVICE, DEVELOPER SUPPLY CARTRIDGE, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A developer container includes: an accommodating portion accommodating a developer and being provided with an opening through which the developer is passable; a shutter member for opening and closing the opening; a projection for moving the shutter member; and a guiding portion for guiding the projection. When said projection is pushed in a pushing direction, the projection is moved in a direction different from the pushing direction by being guided by the guiding portion in contact with the guiding portion and thereafter is moved in the pushing direction, thereby to move the shutter member to open the opening. | 11-27-2014 |
20140376972 | SHUTTER MECHANISM, DEVELOPER ACCOMMODATING CONTAINER, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A shutter mechanism capable of opening and closing an opening through which a developer accommodated in a container is movable includes a shutter member movable to open and close the opening; and a limiting member for limiting movement of the shutter member in a direction of opening the opening. When the container is inclined, the limiting member moves to a position where the limiting member limits the movement of the shutter member. | 12-25-2014 |
