Title: Developer for electrostatic image development
Inventor: WATANABE MAKOTO
IPC: G03G9/09
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a developer having stable flowing property and charging property and excellent in development durability by containing a non-oxide ceramic particle as abrasive in toner particle. SOLUTION: A non-oxide ceramic particle is contained as abrasive in toner particle. A fluidizing agent having an average grain size of 0.005-0.5μm is contained independently from the toner particle. The non-oxide ceramic particle has a hardness higher than a general fluidizing agent such as silica, so that a highly hard deposit adhered onto a photosensitive drum can be easily polished and removed. The non-oxide ceramic particle never damages the surface of the photosensitive drum or a developing roller to deteriorate the printing quality regardless of its high hardness, when a one having a proper grain size is selectively used. The non-oxide ceramic particle may be contained within the toner particle, but it is more effective to contain the non-oxide ceramic particle independently from the toner particle.

Title: Ink jet recorder
Inventor: YASUTOMI HIDEO
IPC: B41J2/175
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To retain a good ink supply performance without the influence of ambient temperature by arranging a control means that applies a voltage pulse of a prescribed frequency to a piezoelectric element and increases the temperature of ink in an ink channel when the temperature of ink is found to be below a prescribed temperature. SOLUTION: When the result of detection output by a temperature sensor 340 shows that the temperature of ink falls short of a prescribed temperature, as a piezoelectric element 315 is high frequency driven at a voltage of a level that does not discharge ink, by changing the frequency and voltage of a head driver, ink generates heat and thereby prevents its viscosity from increasing. Therefore, a good ink supply performance can be maintained, and printing speed can be stabilized while maintaining print quality. The piezoelectric element 315 itself also produces thermal energy due to its vibration and increases its temperature. However, as water is cooled by ink separated by a bulkhead 304, a decline in displacement due to temperature increase of the piezoelectric element itself is prevented from occurring.

Title: Directly heat generating type heating roller
Inventor: TAKEOKA TAKESHI
IPC: G03G15/20
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a directly heat generating type heating roller whose temperature unevenness in the direction of an axial center and a peripheral direction is reduced and whose total resistance value is small. SOLUTION: The resistance heating element layer 34 of a heating roller 10 is constituted of two spiral resistor layers 34a and 36b forming double helix. Thus, the total resistance value R of the resistance heating element layer 34 is given by the combined resistance of two spiral resistor layers 34a and 34b juxtaposed, and the total resistance value R is reduced in accordance with the number of layers without reducing the resistance values Ra and Rb of the spiral resistor layer 34a and 34b. Thus, the total resistance value R is reduced without causing the increase of the temperature unevenness in the peripheral direction or the direction of the axial center in the case the width dimensions of the spiral resistor layers 34a and 34b are made larger or the overall lengths of them are made shorter.
