摘要:
An image forming apparatus capable of enhancing the accuracy of the scanning position of a laser beam to thereby obtain a more precise image. Optical sensors detect reflected light from a surface of a photosensitive drum. During image formation, the apparatus detects the scanning speed of the laser beam in a main scanning direction based on detection signals from the respective optical sensors in each of divisional sections of an image forming area in the main scanning direction. The apparatus corrects magnification of the image in the main scanning direction, based on results of detection of the scanning speed of the laser beam in the main scanning direction.
摘要:
A hybrid type image forming apparatus capable of forming a high quality image by using two image forming units having different resolution from each other, perform high throughput image forming by selecting most suitable image forming method or methods depending upon a kind of input image data, and reducing its running cost. In the apparatus, input image data of resolution of 300 dpi is separated into monochromatic image data and color image data. The monochromatic image data is converted into that of 600 dpi so that four pixels of an image of 600 dpi make one pixel of an image of 300 dpi. Then, a monochromatic image is formed on the basis of the monochromatic image data of 600 dpi by the image forming unit employing the electrophotograph method. A print medium on which the monochromatic image is formed is conveyed to the image forming unit employing the ink-jet printing method where a color image is formed on the basis of the color image data of 300 dpi.

An image information transmitting apparatus comprises an image output unit for outputting image information, a modulation unit for pulse-frequency modulating the image information from the image output unit and a demodulation unit for demodulating the modulated signal from the modulation unit to form the image information. The demodulation unit discriminates a signal content by a time interval from a rise to a fall or vice versa of the input modulated signal.

摘要:
An image processing apparatus has CCDs for reading image data of an original, an edge detector for detecting edges of an area specified on the original with a loop or marks of a specific color, an area detector for detecting the specified area, memories for storing the image data read by the CCDs, and a data selector and a data switching circuit for selecting the image data read by one of the CCDs which is to be supplied to an inkjet head for recording. For preventing contamination of the original, the loop or marks can be drawn on the original through an original cover including a transparent or semitransparent sheet member facing the image of the original. Images inside and outside the area or areas can be selectively reproduced in various combinations of the normal mode, red output modes involving different types of color conversion, and extinguishing mode. Image data from another source which is stored in another memory can be inserted at a desired part of the reproduced copy.

摘要:
A connecting pin pivotally connects together the first frame and the second frame of a process cartridge including the first frame supporting an electrophotographic photosensitive drum and a second frame supporting a developing device for developing an electrostatic latent image formed on the electrophotographic photosensitive drum, and detachably mountable to the main body of an image forming apparatus. The pin is formed of a metallic hollow material, having slits defined by opposed edges of the metal material, and has formed on the metallic hollow material a restraining portion having a leading end as a bending proximal base with respect to the direction of insertion of the connecting pin and an outwardly extending trailing end.
