IMAGE FORMING APPARATUS THAT CONTROLS JETTING OF TONER, IMAGE PROCESSING APPARATUS, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM

摘要

An image forming apparatus which is capable of obtaining stable and satisfactory cleaning performance and fixing performance without holding, in an image forming unit which forms an image on a recording material based on a video signal, data for performing maintenance of the image forming unit. A synchronization signal output from the image forming unit and indicative of timing with which the video signal is output is detected. It is determined whether the synchronization signal is a normal synchronization signal for outputting a video signal for use in forming an image on the recording material or a pattern synchronization signal for outputting a pattern signal that is a video signal for use in performing maintenance of the image forming unit. When the synchronization signal is the normal synchronization signal, the video signal is output. When the synchronization signal is the pattern synchronization signal, the pattern signal is output.

1. An image processing apparatus capable of communicating with an image forming unit that forms an image on a recording material based on a video signal, comprising:
a detection unit configured to detect a synchronization signal output from the image forming unit and indicative of timing with which the video signal is output; a determination unit configured to determine whether the synchronization signal detected by said detection unit is a normal synchronization signal for outputting a video signal for use in forming an image on the recording material or a pattern synchronization signal for outputting a pattern signal that is a video signal for use in performing maintenance of the image forming unit; a video signal output unit configured to, when said determination unit determines that the synchronization signal is the normal synchronization signal, output the video signal for use in forming an image on the recording material; and a pattern signal output unit configured to output the pattern signal when said determination unit determines that the synchronization signal is the pattern synchronization signal.
