IMAGE FORMING DEVICE AND PROGRAM

To provide a technique that can perform processing as desired by a user, when a first image and a second image cannot be superimposed on each other as intended by the user.SOLUTION: When receiving a first image formation instruction including information for requiring a first image and a second image to be superimposed on each other, a first processor, when grasping a first number of pages which is the number of pages related to the first image formation instruction, transmits the first number of pages to a second processor. The second processor, when grasping a second number of pages which is the number of pages related to a second image formation instruction including the information for requiring the first image and the second image to be superimposed on each other, transmits the second number of pages to the first processor. At least one of the first processor and the second processor, when the first number of pages is different from the second number of pages, performs preset processing as processing to be performed when both numbers are different from each other.SELECTED DRAWING: Figure 29 【課題】ユーザが意図した通りに第１画像と第２画像とを重畳することができない場合に、ユーザが望むように処理することができる技術を提供する。【解決手段】第１プロセッサは、第１画像と第２画像とを重畳すべき旨の情報が含まれた第１画像形成指示を受信した場合に、第１画像形成指示に係る頁数である第１頁数を把握したときに第１頁数を第２プロセッサに送信し、第２プロセッサは、第１画像と第２画像とを重畳すべき旨の情報が含まれた第２画像形成指示に係る頁数である第２頁数を把握したときに第２頁数を第１プロセッサに送信し、第１プロセッサおよび第２プロセッサの少なくともいずれかは、第１頁数と第２頁数とが異なる場合に、異なる場合の処理として予め設定された処理を行う。【選択図】図２９
