20140341614 | IMAGE FORMING DEVICE PROVIDING ACCURATE POSITIONING BETWEEN EXPOSURE UNIT AND PHOTOSENSITIVE BODY - An image forming device capable of providing precise positional relationship between an exposure unit and a photosensitive body. The exposure unit having an exposure head elongated in a longitudinal direction and having light emitting sections arrayed in the longitudinal direction. The light elements emit light in an optical axis direction. A frame supports the photosensitive body. A positioning protrusion protrudes in the optical axis direction from one of the frame and the exposure unit. A remaining one of the frame and the exposure unit is formed with a positioning part engageable with the positioning protrusion. A biasing unit provides a biasing force that ensures engagement between the positioning protrusion and the positioning part. | 11-20-2014 |
20150023699 | Developer Cartridge - In a developer cartridge, a base portion may be fixed to a surface of one side of a frame, and extend from one end thereof to another end thereof in a second direction orthogonal to the first direction.
