Title: Image forming device
Inventor: OKANO KEIJI
IPC: G03G15/08
Filed: 1990-09-26
Abstract: PURPOSE:To stably form a high density image by carrying out roughening so that the curvature radius of a recessed part formed on the surface of a developer carrier is set at an average developer grain diameter or above. CONSTITUTION:The developer 6 inside a developing unit frame body 4 is carried on a developing sleeve 3 by a magnetic force, and transported while having triboelectrifying charge together with the rotation of the developing sleeve 3. At this time, when the surface of the developing sleeve is roughened by blast processing by a spherical glass bead, a change in the microscope ruggedness of the surface is loosened, so that a contact area with respect to toner is sufficiently enlarged, and a toner grain can obtain a sufficient triboelectrifying charge. Therefore, at least, the curvature radius of the recessed part is set at the average developer grain diameter or above, and 10-times an average grain diameter, or below. Thus, the dropping of an image density caused by the sticking of the resin powder, etc., of the developer to the surface of the developer carrier, is prevented, and moreover, the high density image is stably formed.

IPC: G03G15/08
Filed: 1985-11-15
Abstract: PURPOSE:To easily operate the copying operation by a user by displaying the remainder number of copiable papers after detection of near-end of a toner. CONSTITUTION:The number of copiable papers corresponding to a prescribed value of the toner remainder is set and stored in a storage subtracting circuit 14. When the toner level falls in accordance with advance of the copying work, the storage subtracting circuit 14 inputs a signal indicating the number of copiable papers to a display device by the detection signal of a near-end detecting sensor 10, which detects a ferromagnetic body in the front end of an arm 8, to display a toner end warning mark 18 and a value 19 of the number of copiable papers. A pulse, which is generated each time when a copying machine executes the copying operation, is inputted to the storage subtracting circuit 14 through an AND gate 15 and the circuit 14 subtracts the number of pulses from the number of copiable papers and outputs the subtraction result to the display device as the remainder number of copiable papers. When the remainder number of copiable papers is zero, a high-level signal is outputted to reset a flip flop circuit 21, and the developing operation of the copying machine is stopped.

Filed: 1987-10-14
Abstract: PURPOSE:To reduce fluctuation in output and to reduce the fluctuation in an ATF error signal by providing a third sample-hold circuit which sample-holds the output of a second sample-hold circuit. CONSTITUTION:The ATF error signal is charged quickly in a small capacity by the second sample-hold circuit 15, and next, it is charged in a large capacity for a long time by the third sample-hold circuit 18. In other words, the second sample-hold circuit 15 charges quickly the output signal of a differential amplifier 13 in the small capacity. The third sample-hold circuit 18 charges the second sample-hold output in the large capacity for a long time. Therefore, it is possible to perform sampling at a regular timing by the second sample-hold circuit 15, and also, to perform re-sampling in the large capacity by the third sample- hold circuit 18. In such a way, the fluctuation in sample-hold output voltage due to a leakage current can be reduced, and the fluctuation in the ATF error signal can be suppressed.
