Title: Control method for latent image potential
Inventor: TSUCHIYA HIROAKI
IPC: G03G15/00
Filed: 1981-04-01
Abstract: PURPOSE:To decrease the time when the first copy is obtained, by measuring the surface potential of a photoreceptor and carrying out the control turn when the power supply is applied and after an image is formed in order to set the charging degree, etc. close to the target value. CONSTITUTION:The surface potential of a drum is measured after a preturn is carried out to smooth the surface of the drum after a fixing heater is heated up by the application of a power supply. The control turn is carried out to set the charging degree, etc. close to the target value, and then the drum is stopped. With push of a copy button, the copy turn is secured immediately after the preturn to secure the control turn after the copying is over. Then the control value is corrected for the charging degree and the exposure value for the next copy, and the drum is stopped after an after-turn. As a result, the time to obtain the first copy can be decreased by the time of the control turn in comparison with the conventional method in which the copy turn is carried out after the control turn.

Title: Thermal head
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1990-03-01
Abstract: PURPOSE:To improve the pulse lifetime and printing durability of a heating element by a method wherein a thermal head is sectioned into a plurality of heating elements by means of a common electrode adjacent to a heating element layer, and one individual electrode is connected to an approximately central part of each heating element so that a gradient is formed in current density of each heating element. CONSTITUTION:Each individual electrode 4b electrically connected to an individual lead wire 15 via a thin film heating resistor 3 is distributed in a space 13 enclosed with a common electrode 4a. Current density at a heating dot 3A of the heating element 3 has such gradient as the current density decreases toward the common electrode 4a and increases toward the individual electrode 4b. Therefore, upon electrification to the heating resistor 3, the heating dot 3A near the individual electrode 4b of high current density has higher temperature increase rate than the heating dot 3A near the individual electrode 4b of low current density, and it quickly reaches temperature capable of melting ink of an ink ribbon. Therefore, by controlling electrification time to the heating element 3, gradation expression which varies printing density can be performed.
