Problems solved by technology

[0007] The guide ribs of conductive endless belts such as the above-mentioned intermediate transfer belts require flexibility (prevention of secondary shape (reform), prevention of bending fatigue), abrasion resistance (prevention of abrasion powder), and low coefficient of friction (prevention of protruding, prevention of viscous sliding) and other performances, as mentioned above, the existing materials for forming guide ribs cannot fully satisfy these performances, and it is desired to develop guide ribs that meet these required performances

Embodiment 1～9

[0039] The various compounding ingredients shown in Table 1 were mixed and kneaded at 60°C for 15 minutes using a kneader to prepare a rubber composition. The rubber composition thus obtained was subjected to roll molding and heated to 150°C to cure it to produce A rectangular parallelepiped guide rib member with a width of 5 mm and a thickness of 1.5 mm.

[0040] The obtained guide rib members were evaluated for coefficient of friction, occurrence of chattering noise, wear resistance, hardness, compression set, and modulus of resilience by the following methods. The results are shown in Table 1.

Abstract

Disclosed is a conductive endless belt (3), on at least one face of which is provided a guide rib (32) protruding in the circumferential direction, with which it is possible to form a guide rib of superior flexibility and low impact resilience, that has excellent wear resistance and a low friction coefficient, and whereby excellent running stability and quietness can be achieved by using millable urethane rubber to form the aforementioned guide rib (32).

Description

technical field [0001] The present invention relates to a conductive endless belt preferably used as an intermediate transfer belt in electrophotographic color printers and the like, and more specifically to a conductive endless belt having guiding ribs for meandering prevention protruding from the inner peripheral surface of the belt. Background technique [0002] Conventionally, an intermediate transfer belt system is known as a system for color printing using toner. [0003] An image forming device that performs color printing in the form of an intermediate transfer belt such as figure 2 Shown: 4 developing devices 1a-1d for developing with black B, yellow Y, magenta M, and cyan C respectively, form toner images in respective colors on photosensitive drums 2a-2d, and transfer images by transfer The roller 5 applies a voltage to the intermediate transfer belt 3 stretched by connecting the photosensitive drums 2a to 2d to adjust the toning of each color (black B, yellow Y,...
