其中，基于第一时间信息确定向图像形成装置30发送验证数据的第二时间信息，可以为上述第二时间信息与上述第一时间信息相同，或者基于上述第一时间信息按照一定算法计算确定第二时间信息，在此不进行限定。
芯片控制单元11通过获取接收到质询信号的第一时间信息，并对第一时间信息进行处理得到第二时间信息，还将第二时间信息加入验证数据中，使得图像形成装置30还可以通过第二时间信息对耗材芯片10进行验证，进一步增加了图像形成装置30对耗材芯片10验证的可靠性。

第一时间信息包括接收质询信号中每字节二进制数据的第一传输时间以及相邻两字节二进制数据的第二传输时间。
如图4所示，t1、t3和t5为每字节二进制数据的第一传输时间，t2和t4为相邻两字节二进制数据的第二传输时间。t1′、t2′、t3′、t4′和t5′为第二时间信息。
图像形成控制单元31具体用于生成发送质询信号的第一时间信息，及用于对验证数据进行解析，得到响应信号。图像形成控制单元31还用于将响应信号与预设响应信号进行比较及将第一时间信息与预设第一时间信息进行比较，当响应信号与预设响应信号一致且第一时间信息与预设第一时间信息一致时，图像形成控制单元31用于耗材为满足预设要求的耗材，由此确定使用耗材进行成像。

本实施例中，图像形成控制单元31同时对响应信号及第一时间信息进行验证，当两者均正确，即响应信号与预设响应信号一致且第一时间信息与预设第一时间信息一致，图像形成控制单元31判断该耗材符合预设要求，通过同时对响应信号的内容及对应的时间进行验证，提高了图像形成装置30对耗材验证的可靠性，上述预设算法为本领域技术人员可知的算法，在此不进行限定。
该实施例中的预设响应信号及预设第一时间信息与质询信号相对应，上述质询信号、上述预设响应信号及上述预设第一时间信息可以预先存储于图像形成装置30中，也可以在将响应信号与预设响应信号进行比较及将第一时间信息与预设第一时间信息进行比较之前，由图像形成控制单元31基于质询信号生成上述预设响应信号及上述预设第一时间信息。
当验证数据为芯片控制单元11通过对响应信号和第一时间信息按照预设算法计算得到时，图像形成控制单元31还将响应信号和第一时间信息的计算结果与预设计算结果进行比较，当计算结果与预设计算结果一致时，图像形成控制单元31确定该耗材为满足预设要求的耗材，由此确定使用该耗材进行成像。在其中一个实施例中，芯片控制单元11具体用于基于预设时钟信号以及预设时间信息向图像形成装置30发送验证数据。

请参考图5，预设时钟信号由图像形成装置30生成。每比特数据位对应一个高电平信号或一个低电平信号，验证数据由多个高电平信号及多个低电平信号组成。高电平信号的保持时间和低电平信号的保持时间为T，如图所示，高电平信号的保持时间对应的延长时间为T1，低电平信号的保持时间对应的延长时间为T2，即第一预设时间和第二预设时间分别为T1和T2，高电平信号的保持时间延长第一预设时间后为T3。高电平信号的保持时间和低电平信号的保持时间为T大于预设时钟信号的保持时间，小于预设时钟信号的一个周期。
芯片控制单元11可以在预设时钟信号的上升沿读取数据总线上的质询信号，从而接收图像形成装置30发送的质询信号，若当前质询信号为高电平，则存储质询信号的数据位为“1”，若当前质询信号为低电平，则存储质询信号的数据位为“0”。
芯片控制单元11可以在预设时钟信号的下升沿向数据总线上提供的验证数据，从而向图像形成装置30发送验证数据，若发送的验证数据的数据位为“1”，则当前验证数据的电平为高电平，若发送的验证数据的数据位为“0”，则当前验证数据的电平为低电平。
将高电平信号的保持时间对应的延长第一预设时间，相当于在预设时钟信号的下降沿，延长第一预设时间后，再向数据总线提供一比特数据位。将低电平信号的保持时间对应的延长第二预设时间，相当于在预设时钟信号的下降沿，延长第二预设时间后，再向数据总线提供一比特数据位。

具体的，图像形成控制单元31用于生成耗材芯片10发送验证数据的预设时钟信号及基于预设时钟信号对验证数据的电平保持时间进行测量，得到测量时间信息。图像形成控制单元31还用于判断测量时间信息是否正确，当测量时间信息正确时，图像形成控制单元31还用于对验证数据进行解析，并确定耗材是否为满足预设要求的耗材，由此确定是否使用耗材进行成像。
当验证数据为芯片控制单元11对响应信号对应的高电平的保持时间延长第一预设时间及对应的低电平的保持时间延长第二预设时间得到时，图像形成控制单元31先测量验证数据的电平保持时间，并对测量时间信息进行验证，当测量时间信息正确时，再对验证数据进行解析得到响应信号，若响应信号正确，则确定耗材为满足预设要求的耗材，由此确定使用该耗材进行成像。
其中，测量时间信息包括第三预设时间和第四预设时间，第三预设时间为高电平信号的保持时间对应的延长时间，第四预设时间为低电平信号的保持时间对应的延长时间，若测量时间信息正确，图像形成控制单元再对验证数据进行解析，得到响应信号，当测量时间信息正确且响应信号正确时，图像形成控制单元确定耗材为满足预设要求的耗材，由此确定使用该耗材进行成像，否则，进行通讯错误的后续处理。
