Abstract:
    The roller alignment device for a developing roller and a squeegee roller of an image forming apparatus comprises: a first supporting block for supporting the shaft of the first backup roller which in turn is disposed opposite to the squeegee roller with the photosensitive belt therebetween; a second supporting block for fixing the shaft of the developing roller and enabling development by the developing roller, and for supporting the shaft of the second backup roller which in turn is disposed opposite to the developing roller with the photosensitive belt therebetween; a roller frame for fixing the shaft of the squeegee roller, and for supporting the first supporting block and the second supporting block while surrounding a portion of the second supporting block; and an elastic member installed for adjusting the centers of the supporting blocks. The assembly tolerance of the conventional block is avoided, and having advantage in that the developing roller and the squeegee roller can be precisely aligned with respective backup rollers.
