A fuel cell cartridge includes a fuel reservoir configured to supply a fuel to a fuel-cell power generation part and has a water-absorber configured to absorb water formed in the fuel-cell power generation part, at least on part of its outer surface. When the cartridge is attached to a fuel cell system, the fuel in the fuel reservoir is supplied to the fuel cell system. A power generation reaction in the fuel-cell power generation part yields electric power and water. The water is easily and reliably absorbed by the water-absorber without leakage to outside of the fuel cell system. The fuel cell cartridge has a simple structure, is easily handled, can easily and reliably recover water formed in the fuel cell, allows the recovered water to be easily disposed of upon recharge of the fuel and exhibits good recyclability.

Toner magnetic powder which uses a resin as a binder and contains a dye is coated by a methyl methacrylate resin, thereby forming a carrier. A developer is formed by such a carrier in which those two components are mixed. An electric conductivity of the impurity extracted water of the carrier due to the pressurization in the pure water is set to 60 .mu.S/cm or less. Namely, the purity is improved so that the electric conductivity of the impurity extracted water of the methyl methacrylate resin due to the pressurization in the pure water is set to 20 .mu.S/cm or less, and the purity is improved so that the electric conductivity of the impurity extracted water of the magnetic powder due to the pressurization in the pure water is set to 60 .mu.S/cm or less, thereby forming a carrier. A carbon addition amount upon manufacturing of the carrier is controlled so that the electric resistance of the carrier is set to a value within a range of 1.times.10.sup.4 to 1.times.10.sup.8 .OMEGA.cm.
