Title: Developing device
Inventor: MASUDA JITSUO
IPC: G03G15/08
Filed: 1994-11-25
Abstract: PURPOSE: To keep the developer carrying force of a developing roller proper. CONSTITUTION: A pressure sensor 45 is arranged near the developing roller 32. The developer is carried to an electrostatic latent image on a photoreceptor 7 by the rotation of the sleeve 32b of the developing roller 32. The pressure sensor 45 detects a change in the pressure of the developer on its surface. When the pressure detected by the sensor 45 is low, the device judges that the developer carrying force is decreased, and therefore it increases the rotating speed of the sleeve 32b by a carrying force control means 60. Consequently an amount that the developer is carried is increased. When the pressure detected by the sensor 45 is high, the rotating speed of the sleeve 32b is decreased. As a result, the amount that the developer is carried is decreased and image density is made stable.

Filed: 1987-11-18
Abstract: PURPOSE:To prevent the staining a tip edge of hard copy by constituting a mechanism to preheat a thermal head while a non-recording area passes through the position of a thermal head and initiate recording at the same time that said area has passed. CONSTITUTION:The dye layer of a dye sheet 1 and the dye accepting layer of an image receiving sheet 2 are held between a thermal head 3 and a platen roll 4 overlapped in such a manner that such layers come into contact with each other at an equal position. Then the platen roll is rotated to move the dye sheet and the image receiving sheet and the preheating is initiated at a slightly delayed timing. In this state, the non-recording area(N) of the dye sheet and the image receiving sheet ale at the position of a thermal head, and the surface temperature of the thermal head continues to rise. Then recording starts when the surface temperature of the thermal head reaches a necessary recording temperature level for transfer Tw. After this, when the non-recording area(N) at the tip has passes, and the tip of a recording area(P) comes to the position of the thermal head, an image information signal is entered to initiate recording. When the recording area(P) has passed and the tip of the non- recording area(N) of the rear end part comes to the position of the thermal head, the recording is terminated. Consequently, the blank at the tip is not stained.
