PHOTOSENSITIVE UNIT AND IMAGE FORMING APPARATUS
First Claim
1. A photosensitive unit comprising:
- a developer cartridge comprising a developing agent carrier that carries a developing agent and a casing that supports the developing agent carrier and accommodates the developing agent;
a photosensitive member disposed so that the developing agent carrier is press-contacted to the photosensitive member, and in which an electrostatic latent image is developed by the developing agent supplied from the developing agent carrier; and
a side wall to which the developer cartridge is detachably attached, whereinthe casing is provided with a pivoting member comprising a pressuring portion applied with an external pressing force and a fitting projection fitted to the side wall, and the pivoting member is configured to be pivoted along a pressing direction for pressing the developing agent carrier toward the photosensitive member when a pressing force is applied to the pressuring portion, or along a pressure releasing direction opposite to the pressing direction, andthe side wall is formed with a fit portion to which the fitting projection is loosely fitted so that a movement of the fitting projection along a pivoting direction of the pivoting member is allowed.

Abstract
A photosensitive unit is described. The photosensitive unit may include a developer cartridge including a developing agent carrier and a casing, a photosensitive member, and a side wall. The casing is provided with a pivoting member including a pressuring portion applied with an external pressing force and a fitting projection fitted to the side wall. The pivoting member is configured to be pivoted along a pressing direction for pressing the developing agent carrier toward the photosensitive member when a pressing force is applied to the pressuring portion, or along a pressure releasing direction opposite to the pressing direction. The side wall is formed with a fit portion to which the fitting projection is loosely fitted so that a movement of the fitting projection along a pivoting direction of the pivoting member is allowed.

13. An image forming apparatus comprising a photosensitive unit, and an image forming apparatus body which the photosensitive unit is configured to be detached from and attached to in a slidable manner, wherein
the photosensitive unit comprises: -
a plurality of developer cartridges comprising a developing agent carrier that carries a developing agent and a casing that supports the developing agent carrier and accommodates the developing agent; a plurality of photosensitive members disposed so that the developing agent carrier is press-contacted to the photosensitive member, and in which an electrostatic latent image is developed by the developing agent supplied from the developing agent carrier; and a plurality of side walls to which the developer cartridge is detachably attached, wherein the respective casing is provided with a pivoting member comprising a pressuring portion applied with an external pressing force and a fitting projection fitted to the side wall, and the pivoting member is configured to be pivoted along a pressing direction for pressing the developing agent carrier toward the photosensitive member when a pressing force is applied to the pressuring portion, or along a pressure releasing direction opposite to the pressing direction, and the respective side wall is formed with a fit portion to which the fitting projection is loosely fitted so that a movement of the fitting projection along a pivoting direction of the pivoting member is allowed, and the image forming apparatus body comprises a pressing force generating unit applying a pressing force to the pressuring portion. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
