１−２７８８４９号）。In addition, after containing silver halide and giving imagewise exposure, heat development is performed to develop the silver halide, the polymerizable compound is simultaneously cured in correspondence with this development, and then pressure is applied to form a visible image. There is a type of photosensitive material that obtains the following, and is particularly preferably used in the present invention. As such,
After thermal development, a color image-forming substance is transferred to an image-receiving material having an image-receiving layer to obtain an image on the image-receiving material.
The photosensitive material has at least a photosensitive silver halide, a reducing agent, a polymerizable compound, and a color image-forming substance on a support, and at least the polymerizable compound and the color image-forming substance are encapsulated in the same microcapsule.

装置内にて所定の画像形成を行なうに際し、感光材料や
受像材料等の画像形成材料の寸度変化は、画像形成プロ
セスが一定であるため、はぼ一定の値となる。When forming a predetermined image in an image forming apparatus using such a sheet-like image forming material, dimensional changes in the image forming material such as a photosensitive material or an image receiving material are constant during the image forming process. Therefore, the value is almost constant.
従って、本発明で、この寸度変化と逆方向に、かつ寸度
変化量と同じ量だけ、予め露光倍率設定をシフトさせて
おき、希望の複写倍率に合致した複写画像を得るもので

露光倍率をシフトする方法としては、ワンショット露光
方式においては、光学系の倍率設定をシフトさせる。
具体的には光学系のレンズ位置を寸度変化量に応じ公知

速度の設定値を公知の方法で変化させてシフトさせる。In addition, in the scanning exposure method, in both the document table moving type and the optical system moving type, the magnification setting in the scanning direction is shifted by changing the setting value of the scanning speed using a known method.
そして幅方向の倍率設定は光学系の倍率設定を変化さ
せてシフトさせる。 この際、走査方向と幅方向とで寸
度変化が異なるときには、スキャニング速度と光学系の
倍率設定の変化量をそれぞれ寸度変化に対応して独立に
変化させればよい。The magnification setting in the width direction is shifted by changing the magnification setting of the optical system. At this time, when the dimensional changes are different in the scanning direction and the width direction, the scanning speed and the amount of change in the magnification setting of the optical system may be changed independently in accordance with the dimensional changes.
また、ワンショット露光方式にてシートの縦、横で寸度
変化が異なるときには、搬送方向または幅方向のみの倍
率を変えるように、シリンドリカルレンズ等の補正光学
系を追加挿入するようにすればよい。Additionally, if the dimensional changes are different in the vertical and horizontal directions of the sheet in the one-shot exposure method, a correction optical system such as a cylindrical lens may be additionally inserted to change the magnification only in the transport direction or width direction. .
このような場合、前述の感光感圧性熱現像画像記録材料

By heat development at 80℃, the photosensitive material is reduced to 1% in each direction.
It shrinks to some extent. In addition, when a paper support is used, the image-receiving material that is superimposed and transferred under pressure is elongated by about 0.2% in each direction.
従って、この場合には、露光倍率を０，８％拡大して露
光することになる。Therefore, in this case, exposure is performed with the exposure magnification increased by 0.8%.
なお、画像形成プロセスが一定でないときには、プロセ
ス条件と複写倍率誤差との関係を予め調べておき、選択
するプロセス条件ごとに露光倍率を上記に準じ選択・設
定できるようにすればよい。Note that when the image forming process is not constant, the relationship between process conditions and copying magnification error may be investigated in advance, and the exposure magnification may be selected and set in accordance with the above for each selected process condition.
