摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus which quickly determines an attached state of a developing device whichever a developing device is attached, a developing device in which a storage medium is mounted or a developing device in which a storage medium is not mounted, and to provide a control method for the image forming apparatus and a control program for the image forming apparatus. SOLUTION: When the last determination result shows that the storage medium is present (Yes in S101), a CPU discriminates whether or not the developing device is attached based on accessing of the developing device to the storage medium (discrimination by a first means). When the CPU discriminates that the developing device is not attached by the first means, it discriminates whether or not the developing device is attached based on an output value from a sensor in which a toner amount of the developing device is reflected (discrimination by a second means). When the last determination result shows that the storage medium is not present (No in S101), the CPU discriminates whether or not the developing device is attached by the second means. When the CPU discriminates that the developing device is attached by at least either the first or the second means, the CPU outputs the determination result about whether the storage medium is present or absent. When the CPU discriminates that the developing device is not attached by the second means, outputs the determination result showing that the developing device is not attached. The determination result is stored in a storage means. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To obtain an image forming apparatus capable of canceling partial distortion of a developer supply roller generated during a continuous stop, without providing a special attaching/detaching mechanism, thereby preventing image quality deterioration. SOLUTION: The image forming apparatus includes a developing device 13 including: a metallic developing roller 31 that is rotationally driven in contact with a photoreceptor drum 11; and the developer supply roller 32 that is formed of an elastic material, and rotationally driven in contact with the developing roller 31. When the partial distortion of the developer supply roller 32 is generated in the state where the rollers 31 and 32 are continuously stopped, the toner is not sufficiently supplied in the distorted portion, then, the image quality is deteriorated. In this case, the rollers 31 and 32 are rotated a predetermined number of times or for a predetermined time in response to user's instruction, so that the distortion of the developer supply roller 32 is canceled.

摘要： PROBLEM TO BE SOLVED: To determine how much amount of carrier is accumulated in a developing tank exceeding the discharge level of a trickle discharge mechanism and avoid breakage of an image forming device by performing a suitable process before a two-component developing agent overflows from a regulation gap when continuously printing and outputting high-printing rate images in the trickle type developing device using the two-component developing agent. SOLUTION: This developing device comprises a stirring member which conveys and stirs the developing agent in the developing tank, and a developing agent carrier. The developing device is equipped with a developing agent supply tank, a discharge mechanism which, when the quantity of the developing agent in the developing tank exceeds predetermined quantity, discharges the exceeding developing agent in the developing tank to the outside of the developing tank, and a calculation means which calculates the quantity of carrier in the developing tank. When it is determined by the calculation means that the carrier integrated value obtained by integrating the quantity of carrier in the developing tank might exceed a predetermined carrier excess containing capacity, a discharge increase operation to increase discharge of the developing agent in the developing tank is performed by the trickle discharge mechanism.
