Abstract
Abstract An image forming process and an apparatus capable of reproducing fine lines or small dots in an image, includes a light beam generator, a driver for driving the light beam generator to form the image on a photosensitive member by scanning the member with the light beam, and a controller for controlling the driver to regulate the intensity of the light beam in accordance with information representing the image for at least one of the preceding and succeeding scanning with the light beam.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
An image forming apparatus for forming an image, based on image information, on a photosensitive member, said apparatus comprising: means for generating a light beam; means for driving said light beam generating means to form an image on the photosensitive member by scanning the photosensitive member with said light beam; and means for controlling said drive means to regulate the intensity of said light beam generated by said light beam generating means in accordance with the image information representing at least one of the preceding and succeeding scanning with said light beam.
Claim 2
Dependent Claim
92 words
An image forming apparatus for forming an image, based on image information, on a photosensitive member, said apparatus comprising: means for generating a light beam; means for driving said light beam generating means to form an image on the photosensitive member by scanning the photosensitive member with said light beam; and means for controlling said drive means to regulate the intensity of said light beam generated by said light beam generating means in accordance with the image information representing at least one of the preceding and succeeding scanning with said light beam.
Claim 3
Dependent Claim
103 words
An image forming apparatus for forming an image, based in image information signals, on a recording medium, said apparatus comprising: means for generating a light beam; means for scanning the recording medium with said light beam generated by said light beam generating means to form an image thereon; means for entering image information signals for the scanning of adjacent scanning lines into said apparatus; and means for controlling the scanning mode of said light beam generating means to control the generation of said light beam thereby in response to said image information signals for adjacent scanning lines during scanning by said scanning means.
Claim 4
Dependent Claim
103 words
An image forming apparatus for forming an image, based in image information signals, on a recording medium, said apparatus comprising: means for generating a light beam; means for scanning the recording medium with said light beam generated by said light beam generating means to form an image thereon; means for entering image information signals for the scanning of adjacent scanning lines into said apparatus; and means for controlling the scanning mode of said light beam generating means to control the generation of said light beam thereby in response to said image information signals for adjacent scanning lines during scanning by said scanning means.
Claim 5
Dependent Claim
42 words
An image forming process which comprises the steps of: scanning lines on a medium to form an image thereon in accordance with image information, and controlling the density of scanning in response to image information for the scanning of adjacent scanning lines.
Claim 6
Dependent Claim
42 words
An image forming process which comprises the steps of: scanning lines on a medium to form an image thereon in accordance with image information, and controlling the density of scanning in response to image information for the scanning of adjacent scanning lines.
