Claims16
A semiconductive belt comprising:
- at least one different resistance portion that is configured to partly differ in surface resistance from surroundings,
- wherein the at least one different resistance portion is at an angle with respect to a direction perpendicular to a belt end portion.
A semiconductive roll comprising:
- at least one different resistance portion that is configured to partly differ in surface resistance from surroundings,
- wherein the at least one different resistance portion is at an angle with respect to a longitudinal direction.
A semiconductive member manufacturing method of forming a semiconductive member by utilizing an extruder, the method comprising:
- performing extrusion-molding by rotating a mouthpiece or a core metal of the extruder so that at least one different resistance portion, which differ in surface resistance from surroundings, is at an angle with respect to an extruding direction, when a semiconductive material, which is put into the extruder and contains an elastic material and an electrically conductive filler, is extrusion-molded
A semiconductive member manufacturing method of forming a semiconductive member by utilizing a press molding apparatus, the method comprising:
- putting a semiconductive material, which contains an elastic material and an electrically conductive filler, into a press die having a die mating portion curved with respect to a heat plate surface of the press molding apparatus;
- and
- performing press-molding under a pressure.
An image forming apparatus comprising:
- a toner image forming unit;
- a transfer unit adapted to transfer a toner image onto a recording material;
- and
- a fixing unit adapted to fix the toner image to the recording material,
- wherein the transfer unit has a semiconductive belt or a semiconductive roll, which comprises at least one different resistance portion that is configured to partly differ in surface resistance from surroundings and to be at an angle with respect to a direction perpendicular to a turning direction.
