    摘要： The present invention provides: a toner kit having a deep toner and a pale toner which are separated from each other, wherein: the deep toner and the pale toner satisfy prescribed conditions for an L*a*b* color coordinate system where a* represents a hue in the red-green direction, b* represents a hue in the yellow-blue direction, and L* represents a lightness; the pale toner and the deep toner to be used in the toner kit ; and a method for forming an image using the toner kit. Thus, the present invention can form a high quality image, while suppressing graininess and roughness over the areas covering from the low density area to the high density area.

    摘要： An image pickup apparatus capable of preventing a decline of resolution of a still image while keeping a dynamic range of exposure control. The image pickup apparatus capable of photographing with changing over a moving image and a still image, includes an iris mechanism for changing an amount of light input to an image pickup element by changing an aperture diameter, a filter unit, having a single density or a plurality of densities, for changing the amount of the light input to the image pickup element by its advancing towards and withdrawing from the aperture diameter of the iris mechanism, a unit for driving the iris mechanism and the filter unit independently, and a control unit for setting the filter unit in one of two types of states such as fully covering the aperture diameter of the iris mechanism and fully withdrawing from the aperture diameter in the still image photography.

    摘要： A magnetic coated carrier suitable for constituting a two-component type developer for use in electrophotography is composed of magnetic coated carrier particles comprising magnetic coated carrier particles comprising magnetic carrier core particles each comprising a binder resin and metal oxide particles, and a coating layer surface-coating each carrier core particle. The metal oxide particles have been subjected to a surface lipophilicity-imparting treatment. The magnetic carrier core particles have a resistivity of at least 1x10 10 ohm.cm, and the magnetic coated carrier has a resistivity of at least 1x10 12 ohm.cm. The magnetic coated carrier has a particle size distribution such that (i) it has a number-average particle size Dn of 5 - 100 µm, (ii) it satisfies a relationship of Dn/σ ≧ 3.5, wherein σ denotes a standard deviation of number-basis particle size distribution of the carrier, and (iii) it contains at least 25 % by number of particles having particle sizes of at most Dn x 2/3.
