20120057912 | Protecting agent-supplying device, process cartridge, image forming apparatus - A protecting agent-supplying device including: a rotation member configured to rotate in a certain direction; an image bearing member-protecting agent containing a fatty acid metal salt and an inorganic lubricant, and being in the form of a solid, wherein the agent is scraped off by the rotation of the rotation member, supplied to an image bearing member for protection thereof, and disposed to have a surface facing the rotation member, which surface has a width G in a direction along the certain direction, and wherein the position X (a center of the width G) is located upstream in the direction along the certain direction from the position Y (a line of intersection between the surface facing and a line extended from the rotational center of the rotation member perpendicular to the surface facing), and a distance d between these positions satisfies a formula 003-08-2012 | |
20120060753 | Image bearing member-protecting agent, protective layer-forming device using the same, and image forming apparatus - An image bearing member-protecting agent including a fatty acid metal salt and boron nitride, wherein the image bearing member-protecting agent contains the fatty acid metal salt in an amount of 60% by mass to 87% by mass, and is formed by compression molding; or an image bearing member-protecting agent including a fatty acid metal salt and boron nitride, wherein the image bearing member-protecting agent contains the fatty acid metal salt in an amount of 88% by mass to 99% by mass, and is formed by melt molding. | 03-15-2012 |
20120063825 | Protecting agent supplying member, protective layer forming device, and image forming apparatus - To provide a protecting agent supplying member, containing a core, and a foam layer formed on a periphery of the core, wherein the protecting agent supplying member is in the shape of a roller, and wherein the foam layer has concavities regularly arranged in a surface thereof. | 03-15-2012 |
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 |
20140037304 | LUBRICANT APPLICATOR, IMAGE FORMING APPARATUS, AND PROCESS CARTRIDGE - A lubricant applicator includes a lubricant, a supply member contactable against the lubricant to supply the lubricant to a target, and a lubricant gauge to detect whether an amount of lubricant remaining is less than a threshold value. The lubricant gauge includes a rotary member rotatable about a shaft, a pressing member to press and rotate the rotary member as the lubricant is consumed, a contact part of the rotary member pressed by the pressing member, and a detection part of the rotary member opposite to the contact part across the shaft of the rotary member. | 02-06-2014 |
20150346638 | POWDER CONVEYING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A powder conveying device, including: a powder conveying path including a curved portion; and a conveying screw, wherein the conveying screw is disposed in the powder conveying path, and includes: a rotation axis portion having flexibility; and a blade portion, where the blade portion is helically formed on an outer periphery of the rotation axis portion, and is configured to convey a powder, wherein the conveying screw includes a conveying screw curved portion located in the curved portion of the powder conveying path, and wherein at least a surface of the blade portion of the conveying screw curved portion includes a slipping layer containing a silicon-containing compound. | 12-03-2015 |
