Processing cassette, image forming method and apparatus

Abstract

The invention relates to a processing box, an image forming device using thereof and an image forming method. A image carrier gyres at prtermined speed to connect with the lubricant coating brush 17a of cleaning apparatus 17, which gyring with the same direction of the image carrier at the contacted location, lubricant is coated on surface of the image carrier. Speed of the lubricant coating brush 17a is set higher than photo-conductor drum 1 as the image carrier, comparing with the situation of the image carrier and ubricant coated parts gyre with the same speed, lubricant amounts of lubricant coated parts is less. The invention prevents increasing torque, generating banded stripe images, enables coated lubricant 17b uniformly on the photo-conductor drum 1, and avoid brush injuries and conjunctiva.

Description

technical field

[0001] The present invention relates to a process cartridge, an image forming apparatus using the process cartridge, and an image forming method. Background technique

[0002] In the process cartridge of the image forming apparatus, in order to prevent the degradation of the image carrier caused by AC charging, etc., prevent the solidification (filming) of toner or additive particles on the image carrier, and improve the transferability Etc., apply a lubricant on the image carrier. Among them, the method of scraping and applying the solid lubricant using a brush roll is generally used.

[0003] Conventionally, the lubricant coating brush roll rotates at substantially the same linear speed in the follow-up direction, that is, in the same direction as the image carrier, at the point of contact between the image carrier and the image carrier. If it is rotated in the reverse follow-up direction, the rotation load will increase, the burden on the drive part will...

Examples

Embodiment 1

[0093] The lubricant application brush roll 17a was composed of acrylic fibers, and solid zinc stearate was used as a lubricant, and was pressed against the lubricant application brush roll 17a with an initial contact force of 500 mN. Lubricant coating brush roll 17a diameter is 12mm, like carrier 1 diameter 30mm, lubricant coating brush roll 17a bites 1mm relative to image carrier 1, therefore, at the part that contacts with like carrier 1, lubricates The substantial diameter of the lubricant application brush roller 17 a was 10 mm, and the linear velocity of the lubricant application brush roller 17 a was set to 1.1 times the linear velocity of the image carrier 1 .

Embodiment 2

[0095] The lubricant application brush roll 17a was composed of acrylic fibers, and solid zinc stearate was used as a lubricant, and was pressed against the lubricant application brush roll 17a with an initial contact force of 1000 mN. Lubricant coating brush roll 17a diameter is 12mm, like carrier 1 diameter 30mm, lubricant coating brush roll 17a bites 1mm relative to image carrier 1, therefore, at the part that contacts with like carrier 1, lubricates The substantial diameter of the lubricant application brush roller 17 a was 10 mm, and the linear velocity of the lubricant application brush roller 17 a was set to 1.1 times the linear velocity of the image carrier 1 .

Embodiment 3

[0097] The lubricant application brush roll 17a was composed of acrylic fibers, and solid zinc stearate was used as a lubricant, and was pressed against the lubricant application brush roll 17a with an initial contact force of 1000 mN. Lubricant coating brush roll 17a diameter is 12mm, like carrier 1 diameter 30mm, lubricant coating brush roll 17a bites 1mm relative to image carrier 1, therefore, at the part that contacts with like carrier 1, lubricates The substantial diameter of the lubricant application brush roller 17 a was 10 mm, and the linear velocity of the lubricant application brush roller 17 a was set to be 1.3 times the linear velocity of the image carrier 1 .
