摘要： A developing apparatus includes a guide member for guiding toner toward an image bearing member bearing an electrostatic image thereon, the guide member having a first end and a second end, a vibration generating device for applying an ultrasonic oscillation to the guide member proximate one of the first end and the second end of the guide member, and a vibration absorbing device for absorbing the ultrasonic oscillation in the guide member at the other one of the first end and the second end, wherein toner is conveyed on the guide member in a direction from the absorbing device to the vibration applying device. In one aspect, the toner is a magnetic toner, and a magnetic field is generated on the guide member at a position opposite a surface for guiding the toner.

摘要： An ultrasonic oscillation is applied in the neighborhood of one end of a guide member for supporting and guiding a powder, so that a transverse proceeding wave is generated in the guide member. The powder moves from the other end of the guide member toward a position of the applied ultrasonic oscillation under the action of this proceeding wave.

摘要： An image forming apparatus includes an image bearing member on which first and second electrostatic images are formed, a first developing device for developing the first electrostatic image on the image bearing member with a first toner, and a second developing device for developing the second electrostatic image on the image bearing member bearing the first toner image thereon with a second toner. The second developing device has a toner carrying member opposed to the image bearing member and carrying the toners thereon. The force with which the first toner, having mixed into the second developing device, is carried on the toner carrying member is smaller than the force with which the second toner is carried on the toner carrying member.
