    • There is described an image forming apparatus, which makes it possible to suppress quality degradation of an image on the basis of a developing electric current profile without optically detecting density of a patch image. The image forming apparatus includes: a developing current detecting sensor to detect a developing current; and a control section that conducts consecutive operations of: creating a detecting-use image pattern for detecting a developing characteristic, by aligning a plurality of image patterns, which are different from each other in density; forming a latent image of the detecting-use image pattern onto the photoreceptor element; finding a developing electric current profile, which represents a transition of the developing electric current flowing during an operation of developing the detecting-use image pattern, from an outputted signal of the developing current; and changing an image forming condition, based on the developing electric current profile found by the finding operation.

    • An image forming apparatus includes: a toner image carrier which carries a toner image thereon; a recording medium selection information input section to which recording medium selection information is inputted to select a recording medium to which the toner image carried on the toner image carrier is transferred; a fog controller which sets a fog control parameter value to control a fogging level of the toner image carrier; and an image forming section which forms the toner image to be carried on the toner image carrier based on the fog control parameter set by the fog controller. The fog controller sets the fog control parameter value so that the fogging level of the toner image carrier when the recording medium selection information inputted corresponds to a coated sheet, is lower than that when the recording medium selection information inputted corresponds to a normal sheet.

    • A small-sized heat resisting high voltage transformer and an ignition transformer using the high voltage transformer are provided and utilize both a heat resistant casting resin and a bobbin, which contain an inorganic filler. The high voltage transformer is capable of producing an output voltage of 10-35 kV and comprises a primary coil, a secondary coil, and a magnetic core, wherein a casting resin is injected into the coil part and subsequently cured. The casting resin and bobbin material used for making the coils have heat distortion temperature of at least 130° C., and contain an inorganic filler. The surface of the bobbin may be pretreated. Thereby, adhesion between a bobbin and a casting resin is enhanced to ensure operating properly under the sever heat cycle condition and provide a small-sized heat resistant high voltage transformer.
