摘要： In an electrophotographic recording apparatus, toner images of different colors formed on a photosensitive belt are transferred in overlapping fashion to an intermediate transfer drum to form a color toner image and the color toner image is transferred to a secondary recording medium by means of a transfer unit and then fixed. The intermediate transfer drum includes an electrically conductive drum substrate and a dielectric layer whose resistance is adjusted to a predetermined range, and the drum substrate is connected to earth potential so that setting of an electric field for toner image transfer from the photosensitive belt may not interfere with setting of an electric field for toner image transfer by the transfer unit. Efficiencies of transfer at the two transfer sections can be improved to provide a color image of high quality and the apparatus can be reduced in size.

摘要： A combination of a thermal printer and an invertible ribbon cassette has a mechanism for preventing a portion of the inked ribbon extending between a supply core and a take-up core of the ribbon cassette from shifting in the direction perpendicular to the longitudinal direction of the inked ribbon with respect to a printing head. The mechanism includes a substantially planar surface of a platen, and a printing head is urged against the planar surface of the platen through the inked ribbon portion and a sheet to which solid ink in the area on the inked ribbon portion is transferred by the printing head. The width of that area on the inked ribbon portion in the widthwise direction of the inked ribbon is at most equal to a half of the width of the inked ribbon. Alternatively, the mechanism includes a detector mechanism operative in response to the variation in diameter of the inked ribbon wound on the supply core for applying a variable back tension in the reverse direction to the tension acting on the inked ribbon portion by the take-up core.

摘要： In the thermal transfer printer for printing with an ink ribbon in plural columns, a center of a flat portion formed on the platen roller of a contact portion of the thermal head and a center of the thermal head are shifted corresponding to an amount of shift of printing position as against a center of width of the ink ribbon. When the printing position is set above as against the center of width of the ink ribbon, the center of the thermal head is set above width (P) of the flat portion being formed on the platen roller of the contact portion of the thermal head. When the printing position is set below as against the center of width of the ink ribbon, the center of the thermal head is set below width of the flat portion being formed on the platen roller of the contact portion of the thermal head. The present invention can prevent the shifting-up or the shifting-down of the ink ribbon at the thermal head in structure in which the center of the ink ribbon width and the center of the printing shift in the plural columns printing.

摘要： A thermal transfer printer wherein the carriage is equipped with the ribbon cassette and the thermal head and has a take-up shaft engageable with the take-up core of the ribbon cassette, and clutch means is provided between the motion converting means and the take-up shaft of the carriage, rotational force is transmitted from said motion converting means to the clutch means, and the clutch means cuts off the transmission of the rotational force to the take-up shaft. The rubbing transfer phenomenon does not occur, since, the ink ribbon starts to travel before the thermal head contacts the platen or after the thermal head separates the platen. It is possible to effect control such that no rubbing transfer occurs even when the thermal head is pressed against the platen to effect printing while the carriage is moving transversely at high speed.
