A developing device, comprising:
- a developing housing having a developer accommodating chamber;
- a developer bearing member which is supported rotatably inside the developing housing, and which holds, on a circumferential surface thereof, a two-component developer composed of a magnetic carrier and toner;
- a toner bearing member which is supported rotatably so as to oppose the developer bearing member in the developing housing, and to which the toner in the developer held on the developer bearing member adheres electrostatically;
- and
- a toner recovery tray which has an opening in the upper end thereof, and which is installed removably in the developing housing below the developer bearing member and the toner bearing member.
An image forming apparatus, comprising:
- an image bearing member;
- and
- a developing device which supplies toner to the image bearing member,
- wherein the developing device includes:
- a developing housing having a developer accommodating chamber;
- a developer bearing member which is supported rotatably inside the developing housing, and which holds on a circumferential surface thereof a two-component developer composed of a magnetic carrier and toner;
- a toner bearing member which is supported rotatably so as to oppose the developer bearing member inside the developing housing, and to which the toner in the developer held on the developer bearing member adheres electrostatically;
- and
- a toner recovery tray which has an opening in the upper end thereof, and which is installed removably in the developing housing below the developer bearing member and the toner bearing member.
