Problems solved by technology

[0018] When the amount of lubricant consumed changes more than the appropriate amount, the lubricant may be used up earlier than planned, and the photoconductor drum, etc. may not be properly protected.
On the other hand, when the amount of consumed lubricant changes to less than the appropriate amount, the necessary amount of lubricant cannot be applied to the surface of the photosensitive drum, and the photosensitive drum, etc. cannot be properly protected.

[0106] Figure 9 It is a diagram showing another example of the functional configuration of the image forming apparatus 1 . Figure 10 It is a figure which shows the example of pressing force data 6C.

[0107] The size of the solid lubricant 12F1 decreases as the brush 12F2 scrapes the lubricant from the solid lubricant 12F1, and the distance between the solid lubricant 12F1 and the brush 12F2 increases. Then, the spring 12F3 extends in the direction of the solid lubricant 12F1, and the force (hereinafter referred to as "pressing force") of the spring 12F3 to press the solid lubricant 12F1 becomes weaker accordingly. As a result, it becomes difficult for the brush 12F2 to scrape off the lubricant from the solid lubricant 12F1, and the consumption per unit distance may be less than an appropriate amount.

[0108] Therefore, the process of fine-tuning and determining the brush speed according to the pressing force is performed so that the relative speed of the facing position ...

Abstract

Disclosed is an image forming apparatus capable of sustaining the consumption of a lubricant in an appropriate amount more reliably than in the past even when the processing speed is changed. A photoreceptor drum (12A) and a brush (12F2) for applying a lubricant to the surface of the photoreceptor drum (12A) are provided in the image forming apparatus (1). The surface of the brush (12F2) is movedsuch that the difference between a specified photoreceptor speed, which is the speed at which the surface of the photoreceptor drum (12A) moves, and a specified brush speed, which is the speed at which the surface of the brush (12F2) moves, is within a fixed range, and the speed at which the photoreceptor drum (12A) rotates varies in accordance with the speed at which an image is printed onto paper.

Description

technical field [0001] The present invention relates to a technique for applying a lubricant to a photoreceptor drum of an image forming apparatus. Background technique [0002] Image forming apparatuses having various functions such as copying, scanning, facsimile, and box are spreading. Such an image forming apparatus is sometimes called "MFP (Multi Function Peripherals: Multi Function Peripherals)". [0003] By applying a lubricating material to the photoreceptor drum of the image forming apparatus, components such as the photoreceptor drum itself and the intermediate transfer belt in contact with the photoreceptor drum are protected from abrasion. The invention of applying a lubricant to a photoreceptor drum is disclosed in the following patent documents. [0004] The image forming apparatus described in Patent Document 1 has: a lubricant application unit having a rotating member that grabs a solid lubricant and applies it on the surface of an image carrier; a storage ...
