ABSTRACT:
An imaging material providing device of the present invention comprises: means for carrying imaging material particles charged to a first polarity, the imaging material carrying means having a portion formed of elastic material for holding the imaging material particles; means for receiving imaging material particles, the imaging material carrying means being disposed apart from the imaging material carrying means with a gap therebetween and being charged to a second polarity opposite to the first polarity so that the imaging material particles may be electrostatically attached onto the imaging material receiving means; means for elastically deforming the elastic portion of the carrying means, the imaging material particles being introduced into the gap when the deformed elastic portion is restored; and means for generating an electric field in the gap and electrostatically attracting the charged imaging material particles in a direction toward the imaging material receiving means.
