Eight storage battery cells 11.sub.1 to 11.sub.8 making up a storage battery cell group 2 can be connected selectively to a voltage-correcting storage battery 12 through nine cell change-over switches 13.sub.1 to 13.sub.9, four polarity-inverting switches 14.sub.1 to 14.sub.4 and a current-limiting resistor 15. When the voltages of two or more of the storage battery cells 11.sub.1 to 11.sub.8 are different, the voltages of each of the storage battery cells 11.sub.1 to 11.sub.8 can be equalized by then transferring the charge from a storage battery cell high in voltage to the voltage-correcting storage battery 12 and by transferring the charge of that voltage-correcting storage battery 12 to a storage battery cell low in voltage. As a result, the voltage difference due to the performance variations among the individual storage battery cells 11.sub.1 to 11.sub.8 can be obviated thereby to increase the working voltage range of the storage battery cell group 2 as a whole.

A toner transport screw that is capable of maintaining a smooth and stable transport function. The toner transport screw, in which a helical blade is disposed on the circumference of a rotating shaft, has at least one spiral direction reversal part formed by connecting the respective ends of a first blade part and a second blade part, the directions of spiral of the first blade part and the second blade part being in opposite directions. A passage, which allows the toner to pass through the blades in the circumferential direction of the rotating shaft, is formed in the spiral direction reversal part.

A development device includes a developer carrier, a bearing member, a biasing member, and a guide. The developer carrier supplies a developer to an electrostatic latent image formed on an image carrier to develop the electrostatic latent image into a toner image. The bearing member rotatably supports the developer carrier axially. The biasing member is provided on a side of the bearing member opposite the image carrier to apply a force to the bearing member to move the bearing member and the developer carrier toward the image carrier. The guide is disposed about the bearing member to enable the bearing member to move therebetween and guide the bearing member toward the image carrier. The bearing member includes a rotatable part to rotate and slide over the guide while contacting the guide.
