density is lower than a reference value, a toner replenishing sequence and then a
developer agitation sequence are run.
5. These sequences are repeated up to a maximum of four times until the toner density
reaches the reference value. If the toner density is found to be higher than the refer-
ence value, only a developer agitation sequence is carried out.
