Abstract
A heat-sensitive stencil master making system includes a thermal head having an array of a number of heater elements which extends in a main scanning direction substantially perpendicular to a sub-scanning direction in which the thermal head is moved relatively to heat-sensitive stencil master material when imagewise perforating the heat-sensitive stencil master material. Each of the heater elements is longer in the main scanning direction than in the sub-scanning direction.
