摘要： In examples provided herein, a roller damper comprises a damper body element having mass and having a shape to fit an interior of a tubular roller element. The roller element is associated with a natural frequency. The roller damper also comprises an elastomer support member coupled to the damper body element. The mass of the damper body element and the elastomer support member are selected based on the natural frequency of the tubular roller element.

摘要： In one example, a method for calibrating a position of a charge roller is described. The method may include a processor positioning a first end of a charge roller to a first plurality of index positions, determining a capacitance between the charge roller and a photoconductor imaging plate at each of the first plurality of index positions, determining a first index position of the first plurality of index positions with a greatest change in capacitance, and calibrating a position of the charge roller based upon the first index position.

摘要： A blade-like charging member for charging a surface of an image bearing member. The blade-like charging member includes a charging portion for effecting electric discharge to the surface of the image bearing member and a non-charging portion. The non-charging portion can contact the image bearing member with a gap. At least a part of the non-charging portion is made of a material having a higher resistance than that of the charging portion so as to prevent electric discharge between the non-charging portion and the surface of the image bearing member. The non-charging portion is capable of sliding contact with the surface of the image bearing member over the entirety of an image forming region width of the surface of the image bearing member. The charge portion and the non-charging portion are bonded to each other by adhesive material at a connection interface.

The second electrode has an opening that opens in a first direction in which the first electrode, the insulating material, and the second electrode are arranged. The insulating material has a region limiting space. The region limiting space corresponds to the opening. The region limiting space is continuous with the opening. The region limiting space is a space that opens in a direction in which the region limiting space is oriented toward the opening and that is limited in a second direction perpendicular to the first direction. The first electrode has an anisotropic resistance portion in which a resistance component in the first direction is smaller than a resistance component in the second direction.

摘要： A printer includes a photoconductor, a charge roller, and a positioner. The photoconductor includes an outer surface defining a seam region and a non-seam region while the charge roller is configured to rollingly engage the outer surface of the non-seam region. The positioner is operably coupled to the charge roller and includes a discrete step drive configured to maintain a minimum spacing between the charge roller and the seam region of the outer surface when the seam region passes underneath the charge roller.

摘要： A charging device includes a charging roller, a drive transmission device, and a charging roller cleaner. The charging roller opposes an image carrier driven to rotate and rotates to charge the image carrier. The charging roller cleaner contacts the charging roller to clean the charging roller. The drive transmission device transmits torque from the image carrier to the charging roller, and includes an image carrier gear and a driven gear. The image carrier gear and the driven gear form a gear train to drive the charging roller in response to rotation of the image carrier. The charging roller cleaner is disposed facing a rear surface of the charging roller to prevent displacement of the charging roller due to a force generated by a pressure angle formed between the image carrier gear and the driven gear when the charging roller rotates in response to rotation of the image carrier.

摘要： A charging unit is disclosed capable of reducing undue variation and fluctuation margin of a charging gap, and controlling accurately the proper gap durably over the change of environmental conditions, which is suitably incorporated into an image forming apparatus. The charging unit is configured to charge an image bearing member in a non-contact arrangement, including a charging roller provided with a core shaft, a charging member formed of electroconductive resin integrally disposed on the periphery of the core shaft, and gap holding members formed of insulating resin each disposed at respective ends of the charging member outside an image forming region. The control of the charging gap is feasible by either forming the gap with a charging member having such a materials condition as to satisfy the relation, |G30−G10|×5
