An image forming apparatus includes a plurality of process units, a plurality of latent image carriers, an optical writing unit, an upper cover, and a pitch positioning member. The pitch positioning member including a plurality of abutting portions so as to regulate movements of the plurality of process units in the horizontal direction by abutting each of the plurality of process units. The pitch positioning member including a plurality of notches extending from an upper portion to a lower portion of each of the respective plurality of abutting portions with a predetermined pitch.

An image forming apparatus includes a first member and second member that are formed of different materials. The first member includes a plurality of first abutting portions. The second member includes a plurality of second abutting portions. One latent image carrier or one holding member abuts with one first abutting portion so as to regulate movements of the latent image carrier in a first direction substantially parallel to a sub scanning direction. One latent image carrier or one holding member abuts with one second abutting portion so as to regulate movements of the latent image carrier in a second direction, which is substantially orthogonal to the first direction.
摘要:
An apparatus or an image forming apparatus including a main body having a first supporting leg configured to be connectable to the main body, a second supporting leg fixed to the main body, and the position of the main body to connect the first supporting leg is selectable. The apparatus may be stable on the installation surface if the center of gravity of the apparatus is transformed.

The present invention provides an image forming apparatus which prevents deformation of a structural frame caused by external force or weight of the apparatus itself, when set on a surface such as a conventional desk or floor, prevents image defects such as image deformation and the like without reducing the degree of accuracy of positioning support of respective printing devices inside the image forming apparatus, and furthermore also makes precise color matching possible while also being low price, easily assembled, compact, lightweight, highly reliable, and capable of obtaining high quality images. The structural frame of the image forming apparatus includes side wall portions made of resin and provided on either side of the apparatus, and at least two connectors formed from metal, for connecting the side wall portions, an image forming unit being supported by the side wall portions, and the connectors joining the side wall portions in substantially perpendicular and substantially horizontal directions.
摘要:
An image forming apparatus capable of suppressing drop in the write positional accuracy of the optical write while improving the maintenancability of the photosensitive bodies and the peripheral devices thereof, having a printer comprising four processing units each holding, in the inner part thereof, a photosensitive body for supporting a latent image on an endless moving surface, an optical write unit that is movable between an operate position where a write operation is performed for writing latent images on the surface of each of these photosensitive bodies and a retreat position where this write operation is not performed, and a support body for supporting each of the photosensitive bodies of the processing units and the optical write unit, the support body being configured as an integrally molded part by being united at the location for supporting each of the photosensitive bodies of the processing units and the location for supporting the optical write unit from (front-side panel and rear-side panel).
摘要:
In an image forming apparatus, a photoreceptor carries a latent image on its looped surface. An optical writing unit moves between an operating position at which writing of a latent image is performed on the looped surface of the photoreceptor and a standby position at which writing is not performed. A developing device develops the latent image carried on the photoreceptor. A reference position member is located at a reference position for positioning the optical writing unit. A positioning member positions the optical writing unit. A bias coil spring biases the reference position member so that the reference position member contacts the positioning member.
