Filed: 1990-10-16
Abstract: PURPOSE:To attain an image recording imaging the image of high resolution and high density with better reproducibility by incorporating a liquid developer organic fine particles incompatible with the dispersion medium. CONSTITUTION:This developer is a liquid developer formed by dispersing a toner consisting essentially of a pigment and a resin in a dispersion medium having a high insulation property and a low dielectric constant and it incorporates at least organic fine particles being incompatible with the medium. In this case, the liquid developer has large coagulation force at the transferring time to a transferred medium, since it has a structural viscosity and also the coagulation force is increased rapidly by heat-drying prior to the process.

At this stage, the limit value is measured as a shearing load. A vertical load and a shearing stress are obtd. based on each above described value. The toner is evaluated based on a coefft. of friction calculated from the vertical load and the shearing stress. Thus, evaluation of characteristics of a toner is attained exactly.

CONSTITUTION:It makes the boundary 82 between hot water and lower-temperature water rise to draw off hot water from an upper part of a hot water storage tank 56 and replenish the storage with lower-temperature water from the bottom, whereas the boundary 82 is made to remain at a certain height by drawing off lower-temperature water from the bottom through a circulating line 59 and after heating it by a hot water-supplying heat exchanger 3 and by an exhaust heat recovery device 46 by supplying the heated water from above. The boundary 82 is made to fall with increase of the body of hot water 80 by circulating more water through the hot water-supplying heat exchanger 3 than what is drawn off through a hot water supply line 63 or by using the heat exchanger 3 to a higher capacity. When increased use of hot water causes the boundary 82 to rise fast, the supply of hot water from the hot water-supplying heat exchanger 3 is increased so that the runout of the hot water is prevented. In such cases the rise of the boundary 82 can be detected as the result of temperature sensing by thermistors 78a, 78b.
