    摘要： A latent electrostatic image developing device comprising a developer receptacle for holding a developer composed of carrier particles and toner particles, a developer applicator means for holding part of the developer in the developer receptacle on its surface and carrying it to a developing zone, a developer agitating means, a toner particle receptacle for holding toner particles and a toner particle feed means for feeding the toner particles from the toner particle receptacle to the developer receptacle. The developer applicator means has a plurality of agitating blades extending in the widthwise direction, and a cut is formed in at least some of the agitating blades. The developing device also has a developer detector for detecting the consentration of the developer, and the developer detector detects the concentration of the excess of the developer removed from the developer applicator means. The developing device also has a partitioning plate for conducting the excess of the developer removed from the developer applicator means to the agitating means. The agitating means moves the developer from one side toward the other side, and the partitioning plate moves the developer removed from the developer applicator means form said other side toward said one side.

    摘要： A latent electrostatic image developing device for developing a latent electrostatic image formed on an image-bearing member by applying a developer thereto. The developing device comprises a developer applicator means for holding the developer on its surface, carrying the developer to a developing zone and applying it to the latent electrostatic image in the developing zone and a bias voltage applying means for applying a bias voltage to the developer held on the surface of the developer applicator means. The developing device further includes a detector means for detecting the relative humidity of the environmental atmosphere and a control means for changing the magnitude of the applied bias voltage to a lower value when the detected relative humidity of the atmosphere exceeds a predetermined value.

    摘要： A developing device includes a unit support member attached to an opening formed in a front panel of image forming apparatus, support for supporting the unit between the unit support member and a rear panel of the apparatus with the unit pivotable about an axis parallel to the rotation axis of the photoreceptor, and a guide mechanism for guiding a casing of the unit, whereby when the unit is set in the apparatus, a developing sleeve is put in a first state in which the sleeve is near the photoreceptor, and when the unit is inserted in and drawn out of the apparatus, the sleeve is put in a second state in which the sleeve is spaced apart from the photoreceptor. Also when the unit is set in the apparatus, the sleeve is changed from the first state to the second state and vice versa. Accordingly, the unit is replaced through the front panel of the apparatus with ease, and there is eliminated the necessity to provide an excessive space for inserting and drawing the unit in the apparatus, while preventing the developer from unnecessarily coming into contact with the photoreceptor in the non-developing stages, whereby monocolor developing is assuredly performed.
