摘要:
An image forming apparatus includes a main casing (2); a photosensitive member (27); a process cartridge (17) that can be installed or removed with respect to the main casing along a removal path; a scanner unit (16) located above the process cartridge when the process cartridge is installed in the main casing; a sheet accommodating portion (6) located at a bottom portion of the main casing; a pick-up roller (8) located above the sheet accommodating portion; and a feed path along which a sheet can be conveyed from the sheet accommodating portion to a discharge port. At least a part of the feed path is substantially parallel to the removal path and located between the sheet accommodating portion and the process cartridge when the process cartridge is installed in the main casing; the scanner unit includes a frame including a first portion having a first height and a second portion having a second height that is less than the first height, the second portion being located closer to the pick-up roller than the first portion; and an image forming position (P) where an image is transferred from the photosensitive member to the sheet is located along the feed path at a position lower than an upper surface of the pick-up roller in a direction perpendicular to the removal path.

摘要:
An optical scanner used for an image-forming device to form a color image includes a plurality of photosensitive drums for superimposing a developer image formed on each of the plurality of photosensitive drums. The optical scanner includes a casing, a plurality of light sources, a deflector, an optical system, and a storage device. The plurality of light sources is provided in a one-to-one correspondence with the plurality of photosensitive drums. Each of the plurality of light source emits a laser beam. The deflector is provided in the casing for deflecting the laser beam. The optical system is provided in the casing for guiding the deflected laser beam to a corresponding one of the plurality of photosensitive drums to make the laser beam scan the corresponding one of the plurality of photosensitive drums. The storage device stores a characteristic related to the laser beam scanning the corresponding one of the photosensitive drums.
