摘要:
In a copying machine comprising a photosensitive drum having an amorphous silicon type photoconductive layer, if an image of an original is focussed on the photoconductive layer with a light having a wavelength shorter than 600 nm, the light fatigue of the amorphous silicon photoconductive layer is prevented, and the image memory phenomenon owing to the light fatigue is effectively obviated.

摘要:
A two-component electrophotographic developer for use in developing a latent electrostatic image of a low potential. The developer is composed of a mixture of a magnetic carrier of spherical sintered ferrite particles having raised and depressed portions attributed to the primary particles on their surface, a median size of from 30 to 50 micrometers, an apparent density of less than 2.6 g/cc and an electric resistance, measured in the form of a magnetic brush, of from 6.times.10.sup.4 to 2.5.times.10.sup.6 ohms and chargeable toner particles having a volume inherent resistivity of at least 1.times.10.sup.13 ohms-cm and a specific inductive capacity of from 4 to 6. In a preferred embodiment, the chargeable toner particles have a median size of from 10 to 14 micrometers and are substantially free from particles having a particle diameter of not more than 5 micrometers. The developer can give an image of a high density, a high resolution and excellent gradation without brush marks.

Described herein is an information processing device, information processing method, program storage medium, program, data structure, and manufacturing method for storage medium wherein a user can determine subtitles with certainty. That is, an attribute buffer holds at least font style specifying information which specifies a font style to be applied for a character object for a subtitle held in a character object buffer, and width specifying information which can specify the width of the outline of the character object corresponding to the font style having an outline. In the case that the font style having an outline is specified in the font style specifying information, a font rasterizer obtains font style data of the font style having an outline, updates the font style data based on the width specifying information, and converts the character object into subtitle data, using at least the updated font style data.
摘要:
An information processing apparatus including: a data processing unit which performs copy processing for recording recorded data of a first medium in a second medium, wherein the data processing unit performs processing for referencing copy restriction information received from a management server, comparing the copy restriction information with apparatus setting information set in a memory of the information processing apparatus, determining whether or not the copy processing is permitted in accordance with the comparison result, and copying recorded data of the first medium to the second medium under the condition it is determined that the copy processing is permitted.
