    摘要: A developer contains a set of color toners and black toner for use in a full color image forming apparatus. Each of the color toners contains a color colorant and a first binder resin, and the black toner contains a black colorant and a second binder resin. The difference between softening point and flow starting temperature of said first binder resin is less than the difference between softening point and flow starting temperature of said second binder resin.

    摘要: A marker detecting section detects markers formed at four corners of a block using binary image data of a two-dimensional code stored in a data memory. A marker's approximate center calculating section calculates the approximate centers of the detected markers. A pattern code detecting means detects a pattern code in accordance with format information of the two-dimensional code stored in a format memory. A marker's real center calculating section calculates the real centers of the markers from the detected pattern code and the format information using the error minimizing method. Based on the calculated real centers of the markers, a data code reading coordinate calculating section calculates reading coordinates for reading data dots of address code and data code areas from the data memory.

    摘要: In a system for converting multimedia information to an optically readable code, printing/recording the code on an information recording medium, and reading the code to restore it to the original multimedia information, a read unit optically reads the code. A decoding unit demodulates the code read by the read unit and outputs demodulated data. A reproduction unit performs processing associated with error correction in units of partial data chunks each consisting, as a unit of an aggregate of a predetermined amount of demodulated data output from the decoding unit. An output unit acquires a predetermined number of partial data chunks output from the reproduction unit to form final output data and outputs the data as the recognizable original multimedia information. An error partial data chunk detection units detects an omitted portion or a portion for which error correction by the reproduction unit has failed as an error partial data chunk in units of partial data chunks output from the output unit. A data change unit recognizes the error partial data chunk detected by the error partial data chunk detection unit and changes data of a portion corresponding to the error partial data chunk.
