摘要： A developing unit is intended to have a capability of efficiently exhausting developing powder. The developing unit is constructed to have a developing bath, one or more rollers for development, an exhausting mechanism for exhausting the developing powder out of the developing bath, a shielding member for shielding the exhausting mechanism from the developing bath or exposing it to the developing bath, and a control unit for controlling the rollers, the exhausting mechanism and the shielding member. When exhausting the developing powder, the control unit operates to drive the rollers and then activate the shielding member for exposing the exhausting mechanism to the inside of the developing bath after a certain time is elapsed since the rollers are driven. Further, a pair of rotary bodies may be provided in parallel for opening or closing the exhaust outlet of the developing bath selectively at a proper time.

摘要： A developing unit is configured to develop an electrostatic latent image born on an image bearing member with a developer that has been charged by mixing and agitating toner and magnetic carrier. The developing unit comprises a developing hopper; a developer bearing member; and at least a pair of agitating and conveying members rotationally driven in the developing hopper. The agitating and conveying members are arranged substantially parallel to the developer bearing member and each rotational shaft of the agitating and conveying members is embedded with a magnetic source element whose magnetic poles are laid out so as to produce a magnetic field radially oriented in a particular fixed direction with respect to the agitating and conveying member.

摘要： In a developing device including a developer tank having a developing area tank and an agitating tank, a first agitating member, a second agitating member, a toner hopper, and a toner storing container, a toner replenishing port is formed in an agitating tank, and two flows of the developer are produced by a rotation of the first agitating member provided with a first agitating blade and a second agitating blade, from both ends of a longitudinal direction of the developer tank to a vicinity of the toner replenishing port. These two flows collides with each other in a vicinity of the toner replenishing port to produce a pulsation flow of the developer from the toner replenishing port into the toner storing container through the toner hopper.

摘要： A developing device of an electrophotographic copier is structured separably into two mutually attachable and internally connected sections. One of these sections is disposed adjacent to the copier's photoreceptor and contains a developing roller and the other section distal from the photoreceptor is made of a relatively inexpensive synthetic resin material, including a stirrer roller. When the developing agent is spent, the two sections are separated and only the second part with the stirring roller is discarded for replacement. In order that the spent developing agent can be effectively collected, a bar magnet may be inserted into a chamber formed inside the shaft of the stirrer roller to make use of its magnetic force or a scrapper may be provided to scrape off the developing agent remaining attached to the developing roller. In the case of a clam shell type copier with a top part of the main body made openable rotatingly with respect to its base part, the developing device becomes tilted when the copier is opened for its replacement. A device for shaking the tank can effectively cause the developing agent remaining inside to move into the lower section of the device for easy collection.

摘要： A transfer device and an image forming apparatus capable of forming an image of smooth image quality with little uneven density, are provided. An alternating voltage is applied so that a first period in which a first peak-to-peak voltage Vpp(1) is applied and a second period in which a second peak-to-peak voltage Vpp(2), lower than the first peak-to-peak voltage, is applied are alternately repeated. In the alternating voltage to be applied, a transfer side potential to shift a toner from an intermediate transfer belt to recording paper sheet and an opposite transfer side potential to shift the toner from the recording paper sheet to the intermediate transfer belt are applied so as to alternate with each other. When f1 denotes a frequency of the first period and f2 denotes a frequency of the second period, f1=f2 is satisfied.
