DEVELOPING DEVICE AND IMAGE FORMING APPARATUS

摘要

A developing device includes a developer including a toner, a developer carrier to carry the developer to an image forming area opposing to a latent image bearing member with rotate, a development casing storing the developer, and a developing bias applying member to apply a developing bias to the developer carrier. There is a contacting part to contact a contacting member grounded electrically and disposed at the development casing, and a gap adjusting member to form a gap between the gap adjusting member and the developing carrier. The gap adjusting member is disposed downstream of a rotating direction of the developer carrier. The development casing is conductive, and an insulation member to insulate the gap adjusting member from the development casing is disposed between the gap adjusting member and the development casing.

1. A developing device for use with developer including toner, comprising:
a rotatable developer carrier to carry the developer to an image forming area opposing to a latent image bearing member; a development casing to store the developer; a developing bias applying member to apply a developing bias to the developer carrier; a contacting part to contact a contacting member grounded electrically and disposed at the development casing, and a gap adjusting member to form a gap between the gap adjusting member and the developing carrier and disposed at a position which is downstream of a position of exposure of the developer carrier, relative to a rotating direction of the developer carrier, wherein the development casing comprises walls which include an electrically conductive material, and an insulation member to insulate the gap adjusting member from the development casing is disposed between the gap adjusting member and the development casing.
