Abstract
A heat developing method having the steps of: initially making the overall surface of a heat developing photosensitive material or a photosensitive and thermosensitive recording material (hereinafter called a “heat developing recording material”) to a predetermined temperature not lower than a glass transition temperature and not higher than heat development start temperature; and performing heat development.
Claims9
A heat developing method comprising the steps of:
- initially heating an overall surface of a heat developing recording material on a base layer to a predetermined temperature that is not lower than a glass transition temperature and not higher than a heat development start temperature;
- and
- performing heat development,
- wherein the glass transition temperature is a glass transition point of the base layer,
- wherein the step of initially heating comprises a step of heating a plurality of portions of said heat developing recording material, plurality of portions are formed along a width of the heat developing recording material, and wherein the width is perpendicular to a conveying direction of the heat developing recording material.

A heat developing apparatus comprising:
- a recording portion for exposing a heat developing recording material or a photosensitive and thermosensitive recording material (hereinafter called a “heat developing recording material”) to form a latent image;
- and a heat developing portion for heating said heat developing recording material by a heating medium thereof to perform heat development, wherein
- a previously-heating portion for heating the overall surface of said heat developing recording material to a temperature not lower than a glass transition temperature and not higher than heat development start temperature,
- a plurality of thermosensors for sampling the temperatures of the overall surface of said heat developing recording material, and
- a comparator for performing a comparison whether or not all of the temperatures detected by said thermosensors have been raised to said predetermined temperature are disposed between said recording portion and said heat developing portion, and
- after said comparator has detected that all of the temperatures detected by said thermosensors and said predetermined temperature substantially coincide with one another, said developing operation is started.
