摘要:
A color image forming method of the present invention includes at least an image forming step in which a color image formed by a transparent toner with at least one kind of fine particles of 5 to 30% by volume being contained in a binding resin and a color toner is formed on a transfer material and a heat-fixing step for heating and fixing the color image onto the transfer material. As a result, graininess, color reproducibility, smoothness, and fixing strength are synchronously fulfilled sufficiently without being deteriorated and an arbitrary glossiness can be uniformly reproduced on the transfer material without depending on image density.

An image structure formed on a medium. The image structure is so formed that an angular distribution of surface reflection light beams under the condition that a surface of an image G formed on a medium is irradiated with a slit-transmitted light beam satisfies the following three characteristics: (1) an angle A corresponding to a half value of a reflected light peak is not smaller than unity but not larger than twice as large as a reference angle A0; (2) the ratio ΔXGWS/ΔXGWS0 of the value of WS of center-of-gravity fluctuation to the value of reference WS0 of center-of-gravity fluctuation is not larger than 10; and (3) an angle B at which the quantity of reflected light becomes {fraction (1/10)} as large as the peak value is in a range of from 3×A0 to 6×A0, both inclusively.

An image forming method for forming a color image having a high glossiness without deteriorating graininess, color reproducibility, and offset resistance utilizes a transparent toner in addition to color toners and varies an amount of developed transparent toner based on the surface roughness of a transfer material such as an average surface roughness obtained from ten values. It is preferable to control the amount of developed transparent toner so that the amount of developed transparent toner M, the surface roughness Rz and specific gravity W of the transparent toner satisfy the following equation:0.15.multidot.Rz.multidot.W.gtoreq.M.gtoreq.0.06.multidot.Rz.multidot.Win which M is an amount of developed transparent toner (mg/cm.sup.2) and corresponds to a weight of the developed transparent toner per unit area on a photosensitive member of a solid image, Rz is an average surface roughness (mm) obtained from ten values and W is a specific gravity of toner (g/cm).

A waterproof construction around a miniature buzzer incorporated in an electronic alarm watch depends on a gasket alone. The construction is such that the gasket can secure a resonant plate without any storage of distortion in the resonant plate. This feature makes it possible to provide the electronic alarm watch having a stable performance for acoustic emission.
