Abstract
An electrographic apparatus includes a laser optical unit for scanningly deflecting a laser beam, a photosensitive member for receiving the laser beam from the laser optical unit to be scanned thereby, and an integrally molded frame provided with a first positioning portion for postioning and supporting the laser optical unit and a second positioning portion for postioning and supporting the photosensitive member.
Claims22
An electrographic apparatus, comprising:
- a photosensitve member;
- an optical unit for projecting onto said photosensitive member image information light formed in accordance with an electric signal;
- and
- an integrally molded frame provided with a first positioning portion for positioning the optical unit and a second positioning portion for positioning said photosensitive member.
An electrographic apparatus to which a process cartridge is detachably mountable, the process cartridge including a photosensitive member to be scanned by image information light and at least one process means actable on the photosensitive member, said apparatus comprising:
- an optical unit for projecting onto said photosensitive member image information light formed in accordance with an electric signal;
- and
- an integrally molded frame provided with a first positioning portion for positioning said optical unit, a second positioning portion for positioning the process cartridge and a third positioning portion for positioning the photosensitive member in said process cartridge.
An electrographic apparatus, comprising:
- a photosensitive member;
- an optical unit for projecting onto said photosensitive member image information light formed in accordance with an electric signal;
- image transfer means for transferring the image from said photosensitive member onto a recording material;
- an integrally molded main frame for positioning and supporting said photosensitive member and said optical unit and said image transfer means;
- and
- image fixing means for fixing on the recording material the image transferred from said photosensitive member, said fixing means being positioned and supported on a frame separate from said main frame.
An electrographic apparatus to which a process cartridge is detachably mountable, the process cartridge including a photosensitive member and at least one process means actable on said photosensitive member, comprising:
- an optical unit for applying image information light formed in accordance with an electric signal onto said photosensitive member for forming an image thereon;
- image transfer means for transferring the image from said photosensitive member to a recording material;
- an integrally molded main frame for positioning and supporting the process cartridge, said optical unit and said transfer means;
- and
- image fixing means for fixing the image on the recording material, said fixing means being positioned and supported on a frame separate from said main frame.
