Recording apparatus
摘要:
A recording apparatus has a donor roller which is driven to rotate at a first peripheral speed and has a layer of uniformly charged fine toner particles, a multistylus recording head for forming a charge pattern on the toner layer, and a transfer roller which is rotated opposite in direction to the donor roller and at a second peripheral speed which is slower than the first peripheral speed. A recording medium is advanced between the donor and transfer rollers at a speed equal to the second peripheral speed, whereby a transferred toner image of increased density is obtained.
