20130315612 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a transfer belt that is stretched on a plurality of support rollers including a backup roller in a loop-like manner and has an outer surface for carrying thereon a toner image; a transfer roller that is brought into pressurized contact with the backup roller across the transfer belt and forms a transfer nip with the transfer belt; a restriction member that is placed upstream of a transfer nip in a sheet conveying direction so as to be switchable between a first state in which the restriction member is brought closer to an inner surface of the transfer belt and a second state in which a distance of the restriction member from the inner surface of the transfer belt is larger than that in the first state; and a control section that switches a state of the restriction member. | 11-28-2013 |
20130343793 | IMAGE FORMING APPARATUS - An image forming apparatus including: a rotatable image bearing member; and a brush roller that rotates in a counter direction to a rotational direction of the image bearing member with a bristle portion being in sliding contact with an image bearing surface of the image bearing member. The bristle portion is inclined forward in the rotational direction of the brush roller. | 12-26-2013 |
20140023387 | IMAGE FORMING APPARATUS - An image forming apparatus including: a transfer belt; a rotational body; a transfer roller that forms a transfer nip part between the transfer roller and the rotational body with the transfer belt therebetween; a pressing section that presses one of the rotational body and the transfer roller against the other of the rotational body and the transfer roller; and a controlling section that controls the pressing section so as to change the pressing direction of the rotational body or the transfer roller in accordance with a predetermined image formation condition. | 01-23-2014 |
20140286657 | IMAGE FORMING APPARATUS AND METHOD OF FORMING TONER BAND - Disclosed herein is an image forming apparatus including: an image bearing member; an image forming section that forms a toner image on the image bearing member; a cleaning blade that makes contact with the image bearing member to remove toner on the image bearing member; and a control section that controls the image forming section to form a toner band on the image bearing member during a non-image formation period, the toner band being composed of toner to be provided to the cleaning blade, wherein the control section controls the image forming section to form the toner band on the image bearing member in such a manner that a toner concentration of the toner band on a downstream side in a rotational direction of the image bearing member is lower than an average concentration of the toner band. | 09-25-2014 |
20150153704 | LUBRICANT APPLICATION DEVICE, CLEANING DEVICE, AND IMAGE FORMING APPARATUS - A lubricant application device includes: a lubricant supply unit; a roller-type rotatable lubricant application member that applies a lubricant agent to a lubricant-applied member, the lubricant agent being supplied from the lubricant supply unit; and a flicking member to be brought into contact with the lubricant application member in a position that is on the downstream side of the lubricant supply unit and is on the upstream side of the lubricant-applied member in the rotation direction of the lubricant application member, the flicking member being brought into contact with the lubricant application member so that the amount of the lubricant agent to be applied to either end portion of the lubricant-applied member becomes smaller than the amount of the lubricant agent to be applied to the middle portion of the lubricant-applied member in the axial direction of the lubricant application member. | 06-04-2015 |
20150277299 | IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM - An image forming apparatus according to the present invention includes: an opposite roller switching mechanism which switches an opposite roller forming a transfer nip to a second opposite roller of which the outer diameter is different from the outer diameter of a first opposite roller; a paper type information acquirer which acquires the type information of a recording medium used; and a controller which controls the opposite roller switching mechanism based on the type information acquired from the paper type information acquirer. | 10-01-2015 |
