Problems solved by technology

[0009] However, based on the internal layout of the device, the sensor cannot be placed at a position facing the solid lubricant in the thickness direction
In this case, it is difficult to detect the movement amount of the solid lubricant in the thickness direction

[0129] An embodiment of an electrophotographic printer (hereinafter, simply referred to as a printer) as an image forming apparatus to which the present invention is applied will be described below.

[0130] First, the basic structure of the printer according to the present embodiment will be described. figure 1 A schematic structure of the printer according to the present embodiment is shown. This printer includes four image forming units 1Y, 1C, 1M, and 1K for yellow, red, blue, black (hereinafter referred to as Y, C, M, and K) as image forming units corresponding to toner image generating units . The image forming units respectively form images using Y, C, M, and K toners of different colors as image forming materials, but are otherwise identical in structure. For example, an image forming unit 1Y that generates a Y toner image will be described. Such as figure 2 As shown, the imaging unit 1Y has a processing unit 2Y and a developing unit 25Y. These units are integra...

[0263] Next, the characteristic structure of the printer according to the second embodiment will be described.

[0264] Figure 51 is an exploded perspective view partially showing the internal structure of the Y solid lubricant applying device 6Y in the printer according to the second embodiment. exist Figure 51 In , the solid lubricant 10Y is fixed on the surface of the holding member 17Y made of C-shaped steel with double-sided tape. The coil spring 19Y urges the back surface of the lubricant fixing surface in the holding member 17Y. The coil spring 19Y presses the solid lubricant 10Y toward the application brush roller 7Y in the direction of arrow A in the figure through the holding member 17Y. The direction of arrow A is a direction along an orthogonal virtual plane perpendicular to the direction of the rotation axis of the application brush roller 7Y and the direction of the center of the brush application roller 7Y.

[0273] Figure 53 An assembled exploded perspective view showing the Y lubricant applying device 6Y in the printer according to the first example. The difference from the printers of the above-described embodiments is that the guide groove is provided as a guide groove GB in which the guide groove is inclined in the direction of arrow A in the figure, that is, the direction in which the coil spring 19Y is biased.

[0274] Figure 54is a schematic diagram showing the movement of the convex portion of the holding member 17Y within the guide groove GD. If the holding member (not shown in the drawing) is biased in the direction of arrow A in the drawing by the coil spring 19Y, the protrusion 118Y provided in the holding member moves in the direction of arrow A in the drawing. In this case, the convex portion 118Y is in contact with one of the side walls of the guide groove GD. Since the side wall is inclined in a direction perpendicular to the direction of arrow A (same as the ...

Abstract

The invention discloses a lubricant applying device, an image forming apparatus, a process unit, and a solid lubricant. The lubricant applying device includes: a solid lubricant; an applying member that applies lubricant powder scraped off from the solid lubricant to an application target; a holding member that holds the solid lubricant; a biasing unit that biases the holding member to bring the solid lubricant on the holding member into contact with the applying member; and a regulating unit that regulates, when a force of a direction orthogonal to an endless movement direction of the applying member is applied from the applying member to the solid lubricant at a frictional surface therebetween, movement of the solid lubricant and the holding member in the orthogonal direction.

Description

technical field [0001] The present invention relates to an application device for applying lubricant powder scraped from a solid lubricant to an application object with an application member whose surface moves in a circular motion, an image forming apparatus using the lubricant application device, and a processing unit. Furthermore, the present invention also relates to a solid lubricant mounted on a lubricant applicator. Background technique [0002] In the prior art, as this type of lubricant applying device, there is known a lubricant applying device that applies lubricant to a photosensitive element corresponding to the object of application (for example, refer to Japanese Patent Application Laid-Open Specification No. 2007-79468 ). Figure 111 Together with the photosensitive element 203, the structure of the relevant part of the lubricant applying device according to the prior art is shown. exist Figure 111 In, the application brush roller 207 as a lubricant applica...
