Abstract: PROBLEM TO BE SOLVED: To provide developer having stable electrification in any environment, to prevent blur of letters or splashing of a toner, and to obtain a good image by incorporating toner particles containing a coloring agent and a binder resin, and as external additives, conductive silica particles and hydrophobic inorg. oxides. SOLUTION: This developer contains toner particles containing a coloring material and a binder resin, and conductive silica particles and hydrophobic inorg. oxides as external additives. By adding conductive silica particles as an external additive to the toner for the developer, charges accumulated in the toner can be leaked to the carrier or a developing device. By using the hydrophobic inorg. oxides together, fluidity of the developer is improved and the contact efficiency of the conductive silica to the carrier or a developing device can be increased. Further, this improves the contact electrification efficiency of the toner and the carrier so that sharp electrification distribution can be kept from low temp. low humidity conditions to high temp. high humidity conditions.

Abstract: PURPOSE:To improve workability with an influence by own weight of a main rope reduced by providing a braking device, which holds the main rope, in at least one of the riding cage side or balance weight side of a pulley in the main rope. CONSTITUTION:Weight of an existing rope 6, positioned between pulleys 13, 17 and a balance weight 15, acts in a direction of supplying a new rope 1, but a movement of the existing rope 6 is impeded by a braking device 20. Next a side of the weight 15 of the rope 6 is cut, and a new construction rope 1 is fed from a drum 18 while loosening the braking device 20, but this feed work is performed by pulling the rope 6 by a worker positioned, for instance, in a side of a guide pulley 17. With this feed of the rope 1, an end in the side of the weight 15 of the rope 6 is collected by a rewinding drum 19 or the like positioned in the vicinity of the lowermost story. During this rewinding work, by the braking device 20 left as properly acting, work is safely performed because a feed speed of the rope 1 by a load of the rope 6 is adjusted.
