Claims12
A mesh belt comprising:
- warps and wefts that are woven with the warps, wherein:
- a first yarn of the warps or the wefts on a transporting surface side of the mesh belt is made of an electrically conductive material,
- a warp density WD, defined by a following formula:
- WD=D×N/25.4×100,
- is between 80% and 150%, wherein D is a diameter of each of the warps (mm) and N is a number of the warps per inch, and
- a portion of the mesh belt is configured to contact a powder material and remove, by the electrically conductive material, a negative charge generated on the transporting surface side of the powder material.
