摘要： A novel development device includes a developer roller, a developer reservoir, a rotatable conveyor, and a replenisher unit. The developer roller is configured to supply toner particles to the electrostatic latent image. The developer reservoir is configured to hold the developer therewithin for application to the developer roller. The rotatable conveyor is configured to rotate within the developer reservoir to convey the developer toward the developer roller. The replenisher unit has a tubular member terminating at a port opening in the developer reservoir. The replenisher unit is configured to direct a particulate material through the tubular member into the developer reservoir via the port. The particulate material is toner particles, carrier particles, or a mixture of toner particles and a given amount of carrier particles. The port is submerged in the developer within the developer reservoir as the rotatable conveyor rotates.

摘要： The present invention provides a development device which does not accumulate the developer at the corners on the internal walls, the process cartridge having such a development device, and the image forming apparatus, without increasing the size of the device or complicating its structure. A curving surface section is provided in at least one of four sections where internal walls in which bearings of the first rotary conveying body and the second rotary conveying body are positioned intersect with internal walls that are parallel to the first rotary conveying body and the second rotary conveying body.
