  • Patent number: 9058740
    Abstract: A state determining device includes a current detecting unit, a state determining unit, and a notifying unit. The current detecting unit detects a current value of a drive current which flows into a drive motor that rotary-drives a driven unit with a drive force according to the drive current. Based on the drive current value detected by the current detecting unit, the state determining unit determines a state of a driving system including the driven unit. The notifying unit notifies a user of a determination result of the state determining unit.

  • Publication number: 20130064567
    Abstract: An image forming apparatus includes an imaging unit, a ventilator unit, and an electrical conductor. The imaging unit incorporates electrically powered equipment to which power is supplied from an external voltage source. The ventilator unit is connectable with the imaging unit to ventilate the imaging unit. The ventilator unit includes a fan and an air duct. The fan generates an airflow. The air duct extends from the fan to direct the airflow between the fan and the imaging unit. The electrical conductor is disposed within the air duct to electrically connect the imaging unit and the voltage source upon connection of the ventilator unit with the imaging unit.

  • Patent number: 5502552
    Abstract: In a developing device for an image forming apparatus, a developing roller has dielectric portions and conductive portions distributed regularly or irregularly over the surface thereof. The surfaces of the dielectric portions are smaller in height than the surfaces of the conductive portions. The difference in height is greater than one-half of the volumetric mean particle size of a toner. A charge opposite in polarity to a charge to be deposited on the toner is deposited on the dielectric portions. The dielectric portions, or recesses, each has a width more than three times as great as the volumetric mean particle size of the toner and a depth less than five times the volumetric particle size. The dielectric portions may be greater in height than the conductive portions and may be implemented as spiral grooves inclined more than 30 degrees relative to the axis of rotation of the developing roller. The developing roller may be moved at a higher linear velocity than a photoconductive drum.
