摘要： 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.

摘要： 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.

摘要： In a toner collecting device of the present invention for conveying collected waste toner to a waste toner storing portion with a toner conveying device, the toner conveying device is positioned at a side opposite to a driveline included in an apparatus body to which the toner collecting device is mounted. A driveline for driving the toner conveying device is not arranged at the side opposite to the driveline of the apparatus body, but the toner conveying device is directly driven by the driveline of the apparatus body. With this configuration, the toner collecting device is capable of driving, e.g., a toner conveying belt or a toner conveying screw arranged at the counter drive side without sophisticating the configuration.
