Electrophotographic copy machine having a temperature compensated time exposure.

摘要

An electrophotograhic copy machine having a machine "ready" portion (14-22) for presenting a machine ready condition and with which an intermediate copy sheet is used for exposure to the output of a light source (8) including a time adjustable control circuit portion (24-38) providing a time period during which the light source is energized. The time adjustable control circuit portion has a temperature sensitive element (72 or 74) for shortening the time period as the temperature within the machine increases and vice versa. Such automatic temperature adjustment compensates the exposure time versus temperature relationship of the intermediate sheet.
