Abstract
The surface layer of an intermediate transfer belt has a concavo-convex pattern formed thereon by spherical resin particles which are independently embedded in the layer so that the embedment rate in the thickness direction of the layer is higher than 50% but lower than 100%.
Claims10
An image forming apparatus comprising:
- an intermediate transfer belt;
- and
- a lubricant applying unit comprising a solid lubricant and a conducting brush configured to apply the solid lubricant onto a surface of the intermediate transfer belt,
- wherein the intermediate transfer belt comprises:
- a resin layer, which is a surface layer of the intermediate transfer belt,
- wherein the resin layer has a concavo-convex pattern formed by spherical resin particles which are fine silicone resin particles or fine acryl resin particles independently embedded in the resin layer so that the embedment rate of the spherical resin particles in the thickness direction of the resin layer is higher than 50% but lower than 100%;
- and
- wherein for each spherical resin particle amongst the spherical resin particles forming the concavo-convex pattern on a surface of the resin layer, a diameter of the spherical resin particle is within a range of ±50% of an average particle diameter of the spherical resin particles.
