Lubricant feeding device, processing cassette and image forming device

Abstract

The invention provides a lubricant feeding device, a processing cassette and an imaging forming device. By using the lubricant feeding device, the processing cassette and the imaging forming device, the shortage of the lubricant for a image carrier does not appear; the image carrier can be supplied with the lubricant constantly and stably; and the changing time of the solid lubricant can be detected correctly. The lubricant feeding device includes a lubricant feeding roller (16a); the solid lubricant (16b) connecting with the lubricant feeding roller in a sliding manner; a retaining part (16c) keeping the solid lubricant; a shell (16f) receiving the retaining component and the solid lubricant and can make the solid lubricant move towards the direction that the solid lubricant connects with the lubricant feeding roller; a pair of returning parts (16g) supported on a disconnection position in width direction in a rotary manner in the retaining component; an enabling component (16h) making the returning parts return to connect with the shell in a pressing manner and enabling the retaining component. The shell (16f) is provided with a guide part (16f10) to limit the reverse of the returning parts (16g).

Description

technical field [0001] The present invention relates to an image forming apparatus using electrophotography, such as a copier, a printer, a facsimile machine, or a multifunction machine thereof, a lubricant supply device provided therein, and a process cartridge. Background technique [0002] Conventionally, in image forming apparatuses such as copiers and printers, the technology of using a lubricant supply device that supplies lubricant to image carriers such as photoreceptor drums or intermediate transfer belts is known (for example, refer to Patent Document 1, 2 etc.). [0003] Specifically, untransferred toner remaining on the photoreceptor drum after the transfer process should be completely removed by a cleaning blade (cleaning device) in contact with the photoreceptor drum. However, when the contact portion of the cleaning blade is damaged (defective) due to friction with the photosensitive drum, untransferred toner squeezes through the gap between the defective cle...

Problems solved by technology

And, when the solid lubricant moves instantaneously in the direction opposite to the pressing direction, the pressing member (rotating member) face-down phenomenon occurs (relative to the brush roller, the solid lubricant and the pressing member are obliquely pressed, and the posture changes, or Relative to the solid lubricant, the pushing member is obliquely crimped, and the posture changes), and thereafter, the lubricant on the brush roller scraped from the solid lubricant may become inaccurate due to the offset contact between the solid lubricant and the pushing member. Uniform

Moreover, if such a problem occurs, the lubricant supplied to the photoreceptor drum by the lubricant supply device will also become uneven, and the cleaning blade will be damaged or poor cleaning will occur locally.
