and a log transfer unit configured to transfer log information of a type specified in the log transfer information, among the log information managed by said log management unit, to a transfer destination specified in the log transfer information, wherein said log transfer unit is configured to count a number of log information pieces that are erased or lost without being transferred among the log information flagged for transfer. ### Claim 2 (depends on 1) The image forming apparatus as claimed in claim 1, wherein said log transfer unit is configured to select transfer destinations available for transfer of log information among transfer destinations having different priority as defined in the log transfer information, and to transfer the log information of the specified type to a destination having highest priority among the selected transfer destinations. ### Claim 3 (depends on 1) The image forming apparatus as claimed in claim 1, wherein said log transfer unit is configured to select one group corresponding to the specified type of the log information from a plurality of groups made up from one or more transfer destinations specified in the log transfer information, to select transfer destinations available for transfer of log information in the selected group, and to transfer the log information of the specified type to a destination having highest priority among the selected transfer destinations. ### Claim 4 (depends on 1) The image forming apparatus as claimed in claim 1, wherein said log transfer unit is configured to select transfer destinations available for transfer of log information separately for each of a plurality of groups made up from one or more transfer destinations specified in the log transfer information, and to transfer the log information of the specified type to a destination having highest priority in each group among the selected transfer destinations selected for each group. ### Claim 5 (depends on 1) The image forming apparatus as claimed in claim 1, wherein said log transfer unit is configured to transfer log information in a consecutive manner or at constant intervals. ### Claim 6 (depends on 1) The image forming apparatus as claimed in claim 1, wherein said log transfer unit transfers a count to the transfer destination specified in the log transfer information, said count indicating the number of log information pieces that are erased or lost without being transferred among the log information marked for transfer. ### Claim 7 (depends on 1) The image forming apparatus as claimed in claim 1, wherein said log transfer unit said is configured to count a number of log information pieces marked for transfer as a yet-to-be-transferred-log count, and to count, as a log lost count, a number of log information pieces that are erased or lost without being transferred among the log information marked for transfer. ### Claim 8 (depends on 7) The image forming apparatus as claimed in claim 7, further comprising a nonvolatile memory unit, wherein said log transfer unit stores the yet-to-be-transferred-log count and the log lost count in said nonvolatile memory unit. ### Claim 9 A method of transferring a log from an image forming apparatus for performing a process relating to forming of an image, comprising: a storing step of storing generated log information in memory based on an event occurrence; a flagging step of generating a flag based on a comparison between the log information and settings in log transfer information to control whether the log information is to be transferred; a transfer step of transferring log information of a type specified in the log transfer information, among the log information stored in the memory, to a transfer destination specified in the log transfer information; and a counting step of counting a number of log information pieces that are erased or lost without being transferred among the log information flagged for transfer, in response to finding that the log information stored in the memory is erased or lost. ### Claim 10 (depends on 9) The method as claimed in claim 9, wherein said transfer step includes: selecting transfer destinations available for transfer of log information among transfer destinations having different priority as defined in the log transfer information; and transferring the log information of the specified type to a destination having highest priority among the selected transfer destinations. ### Claim 11 (depends on 9) The method as claimed in claim 9, wherein said transfer step includes: selecting one group corresponding to the specified type of the log information from a plurality of groups made up from one or more transfer destinations specified in the log transfer information; selecting transfer destinations available for transfer of log information in the selected group; and transferring the log information of the specified type to a destination having highest priority among the selected transfer destinations. ### Claim 12 (depends on 9) The method as claimed in claim 9, wherein said transfer step includes: selecting transfer destinations available for transfer of log information separately for each of a plurality of groups made up from one or more transfer destinations specified in the log transfer information; and transferring the log information of the specified type to a destination having highest priority in each group among the selected transfer destinations selected for each group. ### Claim 13 (depends on 9) The method as claimed in claim 9, wherein said transfer step is performed consecutively each time log information is generated, or performed at constant intervals. ### Claim 14 (depends on 9) The method as claimed in claim 9, wherein a count indicating the number of log information pieces that are erased or lost without being transferred among the log information marked for transfer is transferred to the transfer destination specified in the log transfer information. ### Claim 15 (depends on 9) The method as claimed in claim 9, further comprising: counting a number of log information pieces marked for transfer as a yet-to-be-transferred-log count; and counting, as a log lost count, a number of log information pieces that are erased or lost without being transferred among the log information marked for transfer. ### Claim 16 (depends on 15) The method as claimed in claim 15, wherein the yet-to-be-transferred-log count and the log lost count are stored in nonvolatile memory. ### Claim 17 A log transfer system, comprising: an image forming apparatus to perform a process relating to forming of an image; one or more log collecting servers coupled to said image forming apparatus via a network, wherein said image forming apparatus includes: a log management unit configured to generate log information based on an event occurrence, and to generate a flag based on a comparison between the log information and settings in log transfer information to control whether the log information is to be transferred; and a log transfer unit configured to transfer log information of a type specified in the log transfer information, among the log information managed by said log management unit, to a transfer destination specified in the log transfer information, wherein said log transfer unit is configured to count a number of log information pieces that are erased or lost without being transferred among the log information flagged for transfer. ### Claim 18 (depends on 17) The log transfer system as claimed in claim 17, further comprising a setting server coupled to said image forming apparatus via the network to set the log transfer information. ### Claim 19 (depends on 17) The log transfer system as claimed in claim 17, further comprising a tallying server coupled to said one or more log collecting servers via the network to collect log information from said one ore more log collecting servers.
