    摘要： A thermal image forming process comprising the steps of: (i) bringing an outermost layer of a recording material comprising at least one thermosensitive element, comprising a substantially light-insensitive silver salt and a reducing agent therefor in thermal working relationship therewith, on a support into contact with a heat source; (ii) applying heat from the heat source imagewise to the recording material while maintaining mutual contact to but with relative movement between the recording material and the heat source; and (iii) separating the recording material from the heat source, characterized in that the dynamic frictional coefficient during the contact between the outermost surface of the recording material and the heat source has a maximum value of less than 0.3. The outermost layer in contact with the heat source may be the outermost layer of the thermosensitive element, a protective layer applied to the thermosensitive element or a layer on the opposite side of the support to the thermosensitive element.

    摘要： A method for making an image by means of a direct thermal imaging element, comprising on a support a thermosensitive layer incorporating an organic silver salt and a reducing agent contained in said thermosensitive layer and/or in other optional layers. The imaging element is imagewise heated by means of a thermal head having energizable heating elements. The activation of the heating elements is executed duty cycled pulsewise with the steps of preheating each heating element for a preheating time such that a preheat temperature in the imaging element is reached, which is just below the conversion temperature; selecting a pulse duty cycle such that a maximal density on the imaging element will be reached at the end of the maximal writing time; retrieving from a memory for each individual pixel an individual writing time related to a desired density on the imaging element; and energizing the heating elements with the selected pulse duty cycle for a time related to the retrieved individual writing time.
