Lubricant Supplying Device, Process Cartridge, and Image Forming Apparatus

摘要

A lubricant supplying device includes a compressing spring that has one end coming into contact with a holding member in order to bias a solid lubricant toward a lubricant supplying roller and a casing that covers the outside of the device. Then, the casing includes an opening portion that allows the other end of the compressing spring, having the one end coming into contact with the holding member, to be exposed therethrough, and the casing further includes a cover member that is installed in the opening portion in a removable manner so that the cover member comes into contact with the other end of the compressing spring.

主权项

1. A lubricant supplying device that supplies a lubricant to an image carrier that carries a toner image, the lubricant supplying device comprising:
a lubricant supplying roller that rotates in a predetermined direction and slides on the image carrier; a solid lubricant that slides on the lubricant supplying roller; a holding member that holds the solid lubricant; a compressing spring with one end being brought into contact with the holding member, thereby biasing the solid lubricant toward the lubricant supplying roller; and a casing that covers the outside of the device, wherein the casing includes
an opening portion that allows the other end of the compressing spring, having the one end coming into contact with the holding member, to be exposed therethrough,a cover member that is installed in the opening portion in a removable manner so that the cover member comes into contact with the other end of the compressing spring and determines a biasing force of the compressing spring; and a wall portion that is uprightly formed so as to cover a part or an entirety of an outer peripheral portion of the compressing spring, and are uprightly formed so as to cover a part of the outer peripheral portion of the compressing spring in a non-contact state, wherein a notch portion is formed in the wall portion of the cover member so as not to face a wall surface of the casing when the cover member is attached to the opening portion of the casing.
