What do you mean by "legend characters"? The help page has an example
that shows how to modify a legend label ('title' might be a better
term) using a legend.args list. If you mean the axis labels on the
legend, then use an axis.args list with appropriate cex.axis setting).
E.g.

  image.plot(x, y, z, axis.args = list(cex.axis = 2))

If this is not what you have in mind, then you should provide a 
reproducible example that illustrates the problem.
