An output apparatus for outputting a character or the like by using an outline font comprises: an outline information memory to store outline information which expresses a character by points on the outline; a correction information memory to store correction information to correct a value of the outline information; and a correction unit to correct the outline information stored in the outline information memory by using the correction information stored in the correction information memory, thereby preventing a slight difference of the outline points of the original character from a large difference when the character size is changed, and enabling such a slight difference to be correctly expressed when the character is enlarged.
