Title: Method and device for varying magnifying power of font data
Inventor: MURATA MASAHIKO
IPC: B41J2/505
Filed: 1992-05-22
Abstract: PURPOSE:To simplify a circuit by controlling the read of each line data of a font developed to a bit map at a specified variable power rate, varying power in the sub-scanning direction, controlling the read lock frequency of each line data by the specified variable power rate and varying power in the main scanning direction. CONSTITUTION:A reduction circuit 6 inputs output-signals to an address counter 5 as load clocks at every line completion and sets an output from an adder 7 to the address counter 5 at the time of one third reduction. That is, the number of bytes M of a line is counted, the value of 2M is loaded and data are read from an address corresponding to 2M in the address counter 5. Consequently, the bit data of two line sections are skipped, and data using three lines as one line are output. Accordingly, the sub-scanning direction is reduced to one third. A reduction ratio of one third is input to a latch 4 in the main scanning direction, a clock source 3 is controlled, the clock of a P/S equipment 2 is set in treble, and the main scanning direction is reduced to one third.

Title: Toner and picture forming device
Inventor: GOTO YASUO
IPC: G03G15/08
Filed: 1992-06-15
Abstract: PURPOSE:To obtain a toner having a narrow charge distribution and rapid rise of charge by depositing the fine resin powder and fine silica powder respectively having a specified range of particle diameter on the powder obtained by mixing a colorant in a thermoplastic resin. CONSTITUTION:The fine resin powder having 0.3-0.5mum particle diameter and the fine silica powder having 10-20nm particle diameter are deposited on the powder consisting of a thermoplastic resin and a colorant mixed in the resin. In this case, 0.05-0.35wt.% of the fine resin powder and 0.3-0.4wt.% of the fine silica powder are added. An ester of the acrylic and methacrylic acids and such alcohol as alkyl alcohol are used as the monomer constituting the polymer forming the fine resin powder. When the particle diameter of the silica is small, the charge distribution is widened, and the distribution is narrowed when the silica having 10-20nm particle diameter is used. Toner deposited on the fine resin powder is easily charged by tribo-electrification because of the deposition of the resin powder and the rise of the charge becomes excellent.
