| 主权项 | 1. A developing device comprising: a housing; a photoconductor supported by the housing; a charging roller to charge the photoconductor; a holder slidably installed to the housing and serving to support the charging roller; a pressure member to apply pressure to the holder toward the photoconductor; and a space maintaining member separably installed to an outer surface of the housing and having an intervening piece configured to be fitted between the holder and the housing and disposed on the outer surface of the housing to engage with a portion of the holder protruding outward from the housing so as to cause the photoconductor and the charging roller to be spaced apart from each other. | ||
